The titular band in Beck fits this even better than the Five-Man Band pattern:

Choleric	Melancholic	Supine	Sanguine	Phlegmatic
Ryuusuke (charismatic, ambitious)	Taira (calm, collected)	Saku	Chiba (hot-blooded)	Koyuki (the everyman)

• Only Saku's Supine nature is perhaps not so immediately obvious, but he keeps constantly worrying about his skill level holding the band back, even though he's a really good drummer.

Giroro	Dororo	Keroro	Tamama	Kururu

Kill La Kill has three groups:

• Main characters:

Chol-Sanguine	Ryuko	Hot-Blooded nature and single-minded determination to get the answers she wants out of Satsuki.
Melan-Choleric	Satsuki	Focuses on accomplishing her plans and using whatever means necessary to do so, and cares very little for anything that hinders her progress.
Sup-ancholic	Senketsu	Mostly interested in assisting Ryuko's quest and protecting her from harm's way, as well as try to keep her extreme temper under control.
Sang-Supine	Mako	The Plucky Comic Relief interested in having fun with Ryuko, and seems to know just what to say in a given situation to snap people out of their funk.

• The Elite Four:

Sanguine	Jakuzure	A driest sense of humor. She also takes great pride in the fact that she's known Satsuki the longest.
Choleric	Sanageyama	Fight-happy swordsman interested only in finding opponents that can challenge him.
Melancholic	Gamagoori	Firm disciplinary officer and enforcer of Satsuki's rules, and the most overt in loyalty towards her.
Phlegmatic	Inumuta	Preferring to gather and study as much data as possible rather than take an active field role like the others.

• The Kiryuin Conglomerate:

Sanguine	Mind-Controlled Ryuko	Says her emotions bluntly, taking them (sometimes literally) to the person she speaks to. Ryuko even kisses Nui, showcasing their love for each other. She balances out the others' negative emotions by being compassionate with them and follows after Ragyo by being way over-the-top in battles, but as a negative, mind-controlled into finally finding her wants of an actual family; comes off as harsh to others.
Choleric	Ragyo	The Big Bad of the series and an all-around pompous character when she gets her moments. Showcasing the negatives more than the positives — had abnormally high wants when she was testing her own daughters, but filled with glee when they finally do fulfill them.
Melancholic	Nui	Arguably Co-Dragons with Rei to Ragyo, and the one who gets the most work done initially while Ragyo sits around and controls REVOCS. Showcases the downside by being outwardly nice, extremely crazy inside, and even more insane after normal Ryuko cuts off her arms.
Phlegmatic	Rei	The person able to serve at a moment's notice, and without question. Being however, on the downside, outwardly a cold person, exemplified in the OVA by being a Defrosting Ice Queen when she heard of Ragyo's death, and was able to be swayed by Satsuki.

Kiss Him, Not Me: The main four boys:

Sanguine	Choleric	Melancholic	Phlegmatic
Yuusuke Igarashi	Nozomu Nanashima	Hayato Shinomiya	Asuma Mutsumi

The Legend of Zelda by Akira Himekawa: the flash-animations by Hadouken Dude took this to absolutely hilarious levels:

Melancholic	Green Link	The fearless, determined and uptight leader

Sanguine	Subaru	Genki Girl Pollyanna
Choleric	Teana	natural leader and (former) Tsundere
Melancholic	Erio	Introverted knight-in-training
Phlegmatic	Caro	Other introvert

• The bottom two's personalities actually caused a bit of family drama for their also melancholic adopted mother in the second StrikerS Sound Stage, since their combined introversion caused some communication problems.
• After Striker S, the four Combat Cyborgs who were adopted into the Nakajima family are this. Thus here are Hayate's four Knights and the Combat Cyborgs: 

	Choleric	Melancholic	Phlegmatic	Sanguine
Hayate's Knights	Vita	Signum	Zafira	Shamal
Combat Cyborgs	Nove	Dieci	Clinque	Wendi

• As Nanako is merely the kid version of Kozue.

Team Kakashi in Naruto: Naruto (sanguine), Sakura (choleric), Sasuke (melancholic). Kakashi was also melancholic, as he was the "Sasuke" of his own three-man team as a kid, although he's currently phlegmatic.

A good example is probably Neon Genesis Evangelion:

Choleric	Melancholic	Supine	Sanguine
Asuka	Rei	Shinji	Misato

• Though he rarely appears, Kaworu can fit here as Phlegmatic II since he seemingly has absolutely no internal turmoil whatsoever.

Nerima Daikon Brothers:

Choleric	Melancholic	Phlegmatic	Sanguine
Hideki	Ichiro	Team Pet Pandaikon	Mako

One Piece's main male cast:

Choleric	Melancholic	Supine	Sanguine	Phlegmatic

Sanguine	Melancholic	Choleric	Supine

Saiyuki also has two. For the Sanzo party, Goku (sanguine), Sanzo (choleric), Hakkai (melancholic), and Gojyo (phlegmatic). For Kougaiji's group, Lirin (sanguine) and Kougaiji (choleric). Yaone and Dokugakuji switch off between melancholic and phlegmatic, although neither of them are actually lazy The current lineup of the Taishiro in Samurai Deeper Kyo fits almost flawlessly.

Sanguine	Yuan	Extroverted, fond of wisecracks, and very protective of the people he cares about. Wears red and uses fire techniques.
Choleric	Tokito	Perfectionistic, impulsive, and quick to anger. Wears shades of yellow and fights with a fiercely aggressive energy.
Melancholic	Hishigi	Exceedingly introverted and the epitome of the Stoic, analytical and extremely task-focused; plus textbook signs of severe depression. His color scheme is almost entirely black.
Phlegmatic	Fubuki	Level-headed, cultured and elegant leader of the Taishiro. Color scheme mainly blue and fighting style revolves around water.

Sayonara, Zetsubou-sensei: Kafuka (sanguine), Nami (phlegmatic), Chiri (choleric), and Itoshiki-sensei (melancholic).

• Maria (sanguine), Harumi/Kiri/Matoi/Other relatively sane characters (phlegmatic), Kaere (choleric), and Abiru (melancholic).

School Rumble's main girls, counting Tenma's sister Yakumo:

Choleric	Melancholic	Supine	Sanguine	Phlegmatic
Mikoto	Ari	Yakumo	Tenma	Akira

The Slayers characters fit perfectly into these categories, if you count one of their secondary allies:

Choleric	Melancholic	Supine	Sanguine	Phlegmatic
Lina	Zelgadis	Sylphiel	Amelia	Gourry

Soul Eater

Choleric	Melancholic	Supine	Sanguine	Phlegmatic

Onishi	Ran	Ichise	Doc

Ensemble of five in Tokyo Mew Mew:

Choleric	Melancholic	Phlegmatic	Supine	Sanguine
Ichigo	Minto	Retasu	Genki Girl Bu-Ling	Zakuro

• Ironically enough, Ichigo was at first not happy about leading, but she began accepting her responsibility later on.

The Tower of Druaga

	Choleric	Melancholic	Supine	Sanguine	Phlegmatic
Jil's Group	Melt	Jil	Ahmey	Coopa	Kaaya
Neeba's Group	Fatina	Neeba	Kally	Utu	------

Trigun more often averts this trope in favor of the Lone Hero or the Power Trio. Adding Wolfwood to the cast has instead a subtractive effect, generating a duo dynamic that leaves Meryl and Millie on the sidelines. When they participate equally, they fit the four temperaments.

Choleric	Melancholic	Phlegmatic	Sanguine
Meryl	Vash (a pretend sanguine)	Wolfwood	Millie

Tsubasa Reservoir Chronicle: Sakura/Fay (sanguine), Syaoran (melancholic), Kurogane (choleric).

The four aunts in Umineko no Naku Koro ni. Natsuhi (melancholic), Rosa (sanguine), Eva (choleric), and Kyrie (phlegmatic). Probably works with the uncles and cousins too. Have to try that later.

• The Higurashi girls can be categorized this way. Really, both Shion and Keiichi could fit their position.

Choleric	Melancholic	Supine	Sanguine	Phlegmatic
Shion	Rika	Satoko	Rena	Mion

The original Weiss Kreuz:

Choleric	Melancholic	Phlegmatic	Sanguine
Aya	Omi	Youji	Ken

• Between the choleric personality and being the focus character, casual fans often mistake Aya for being the team leader--it's actually Omi.

Wolf's Rain

Choleric	Melancholic	Phlegmatic	Sanguine
Tsume	Kiba	Toboe	Hige

Yes! Pretty Cure 5 tries to throw us off by having four temperaments among five characters — Nozomi and Urara (both sanguine), Rin (choleric), Komachi (melancholic), and Karen (phlegmatic, though not lazy by any stretch).

• In Fresh Pretty Cure: Love (sanguine), Miki (choleric), Inori (more likely supine), and Setsuna (a mix of melancholic and phlegmatic).
• Heartcatch Pretty Cure: Tsubomi (supine), Erika (choleric), Itsuki (phlegmatic — but like Karen, not lazy by any stretch), and Yuri (melancholic).

Jack	Yusei	Akiza	Crow

Out of the four "Yu's" from Yu-Gi-Oh! Arc V:

Sanguine	Yuya	Aspires to make people smile and peacefully solve conflicts, but can be emotionally unstable
Choleric	Yugo	Hot-tempered and occasionally impulsive, but is ambitious and protective of loved ones
Melancholic	Yuto	Determined, pragmatic, and stoic, but has a self-blaming and cynical streak
Phlegmatic	Yuri	Always level-headed and calm, even when relentlessly hunting people under orders of his leader, or being a comedic plaything
