Top one looks like it has something cleaning out the eyes of the alienheads similar to enchi but it isn't enchi. Maybe red stripe? Can't get a great look at the side of the neck or dorsal stripe from that pic. It is yellow belly complex for sure but something else too.
Second looks like just yellow belly to me.
Last one doesn't look yellow belly to me, it has pretty heavy head blushing and from what I can see some flames, but the belly isn't clean enough. Might be just a really interesting normal.
