I really don't know what is on this album, but a lot of the credits look like they are from very old works, so possibly they are all just "featured" here.

A bit late, but: these are the ending themes for episodes 14 through 26 of the anime, as each episode had a different one.
I have edited the notes of the album so it should be clear now (hope I did it the correct way).
