I gave a joke answer to this in the past about everyone being a bard, but since you brought up multiclass, I'll give a more serious answer 😌 (Also, I'm not super knowledgeable about DND, so forgive me if I give an answer that cannot work with the current game's mechanics.)

Eddy - Cleric
Moriah - Druid/Monk
April - Warlock
Pat - Bard
Chester - Bard/Rogue
Dave - Paladin/Sorcerer
Cliff - Ranger (this is his favorite, but he's played as many different characters)
Trent - Wizard/Artificer
Darrell - Barbarian/Fighter
Skizzy - Rogue/Fighter (also plays a lot of DND and this is his favorite)
