I ran across a comment a bit ago that was wondering why Kingdom Hearts characters have articles here if they're more Square characters, and was wondering how many others felt that way.
As for the real answer: Yes, they are Disney characters, as the series was created as just another alternate universe for staple Disney characters (akin to House of Mouse or Disney Infinity), with the introduction of new ones (Sora, Riku, Olette, Org. XIII, etc.). Copyright is made a little more complicated with the appearance of Final Fantasy characters but the Kingdom Hearts characters themselves are Disney, handled by Square Enix. I know it's not easy to look at people like Xigbar and say "Yeah, that's a Disney character", but he is lol
Avatar, Manga Pokemon, Dragon Ball, Chima, Gargoyles, Lego, and other popular cartoon groups on TV or found at the libraries the few you show in the photo just aren't Disney's own personal style of entertainment they're warrior or ranger or a supernatural hero, not the pure animation Disney creates for his own motion pictures. The cartoons in the photo,they're not the style I'd consider Disney.
Pure cartoons like these never entertain me like Disney's classic animation, they just quickly confuse me, I understand Disney heros better than fighting cartoons like the few you've shown here. A fighting cartoon like those you've shown here in the photo I can't tell who's winning or why the fight started, however with Disney's own personal style of animation I can tell what's going on.
I don't care if it's European or Asian I've just never enjoyed pure cartoon stuff as much as Disney's Animated Movies. Cartoon Channels on TV compared to Animated Characters List related to movies, they're not entirely the same in motion picture. Even the internet shows a different collection, Cartoon / Animated.
