That's what I said -- they're currently all in Fantasyland except for the two that don't belong in EPCOT. I've never counted the live shows at DHS, but if you want to throw them in, sure, although the Little Mermaid show is closed.
I think it's a bit silly to group them in with something like Toy Story or Star Wars. Beauty and the Beast and Snow White are only the same "brand" because they have characters Disney has chosen to label as a princess. They have no other connection to each other, and those princess movies constitute a significant part of Disney's classic catalog.
Beyond that, some of those attractions aren't really about princesses at all; they are just connected to a movie that features someone Disney has decided to call princess. I wouldn't call the Mine Train a princess ride. If they decided to start calling Nala a Disney princess, that wouldn't make Festival of the Lion King a princess attraction -- just like you didn't include the Magic Carpets of Aladdin as a princess attraction, even though Jasmine actually is a Disney princess.
I'm certainly not arguing that they need to build more princess attractions. I'm just pointing out that there's not some huge glut of princess attractions all over WDW. Most of Disney's great attractions have nothing to do with any princess, even tangentially.
