Carol is the Gryffindoriest of Gryffindors. No question. Charging into situations fists first and making stupidly noble sacrifices are the things she does best.
Similarly, Mary is Slytherin through and through. Not because she's a blue-blood—though that doesn't hurt her case—but because she's shrewd and ambitious.
Stiles is really difficult though, because he's got some significant traits that are valued by each of the four houses, so for him, it'd probably come down to what he values most in the moment of sorting or which house he'd want to align himself with. I could write you a whole essay about how my thoughts on which house he'd end up in change all the time, but for your sakes I'll skip to the end and say I've lately been leaning toward Hufflepuff. Why? Because Hufflepuff's are "just and loyal." Stiles's Dad is his only family and he doesn't have many friends, but he is unwaveringly loyal to the people he cares about, and it's what ends up driving so many of his actions.
