Kida is the only one of those who's a Princess and she'd be a better fit in Tomorrowland or maybe Adventureland.
I actually think they should all be spread out a bit more. Tiana is good in New Orleans, not let's get Pocahontas an area in Frontierland. There's almost no Native American representation anymore. Mulan would be cool too in Adventureland (although she's not a real Princess either).
I like Kida in adventure land rather than TL, but she can fit there too.
