Is Alice from wonderland a ディズニー princesses?

Nope, she's a ディズニー heroine like Megara, Esmeralda, Kida, Anna, Elsa and others

No, Alice isn't a ディズニー Princess, she's a ディズニー Heroine.

The ディズニー Princess (or DPs) are in order;
Snow White
Cinderella
Ariel
Belle,
Jasmine
Pocahontas
Mulan
Tiana
Rapunzel
Merida

Anna and Elsa were suppose to 登録する but because アナと雪の女王 got so popular, they never did. Moana might join, but that's yet to be seen.

As for the difference between DPs and ディズニー Heroine (DHs) are;

1. Most of the DPs 映画 have done well at the box office. There's one または two DPs 映画 that didn't do well, but are still well known. As for the DHs, their moves are either not that well known (Hercules) または too dark (The Hunchback...)

2. The DPs either start out as princesses (Snow White, Jasmine) または are made princesses によって the end of the film (Cinderella, Belle). ムーラン and kinda Pocahontas don't really follow this one.
However, ムーラン is included because the line-up needed a Chinese person, because she's saved China and also because The Emperor in the movie もっと見る または less 発言しました she now had high status because of her actions.
As for Pocahontas, she's kinda sorta a princess if あなた twist it around a bit.

I'm sure they're もっと見る differences, but those are the biggest ones (I think).
