If you look under the details of the video, it list them all

I only recognized one; revolutionary girl utena; the movie (the one with the pink haired girl and the purple haired girl) though i don't recommend you watch the movie if you like understanding what's going on. watch the anime instead. And if you can get your hands on the manga, it is one of the best shoujo mangas ever made.
