Going down the Main Character List on Wikipedia:
Ms. Frizzle: turns into a Mad Hatter: Intelligent, Talkative, and Good-Natured, but with a loose grasp of reality and a habit of devolving conversations into non-sequiturs
Arnold: picked up by a Oomukade: socially anxious and feeble Jew-boy, they conflate each other's shut-in tendencies and finally get around to "staying in bed today"
Carlos: picked up by a Cheshire: reasons already established
Dorothy: Turns into a Hakutaku: by-the-book teacher's pet who unironically likes studying
Keesha: Probably just turns into a basic Succubus: she has the least developed personality of the main kids, and her one point of trivia is that she's the only kid to participate in every field trip in the show, so it makes sense that she's the vanillabait.
Pheobe: Turns into a Troll: has the most gentle demeanor of all the kids, and it would make her lack of talent at plant cultivation ironically funny
Ralphie: Picked up by a Salamander: Huge on sports and a bit of a delinquent, he'd make it work if he takes things more seriously.
Tim: picked up by a Leanen Sidhe: the "artsy" kid, always writing about or filming the class trips, she'd appreciate that.
Wanda: Turns into a Hinezumi: Tomboy who gets in over her head and needs bailing out often.
Janet: turns into a Danuki: Related to Arnold, who I repeat is a fucking Jew, and is an attention-seeking bitch, what else needs to be said?
Also, if the non-humans are affected:
Liz the class pet Chameleon: would become a midget Sahuagin and continue being Ms. Frizzle's mute lackey
The Bus: A particularly fuckhuge Sandworm with powerful shape-shifting wizardry.
