That have been released, yes.

Crocodile's extended ending is really only for the transition to Beautiful Burnout, so I wouldn't consider it substantially different from what's on the album.

Beautiful Burnout, on the other hand, has a whole structured beginning that was edited out in lieu of mixing with Crocodile on the album.

As for unreleased stuff, when played live, Boy, Boy, Boy has additional lyrics and jamming and a proper ending.

Also, I would not be surprised if longer edits existed for Glam Bucket and Faxed Invitation.
