Anyone care to identift these juvenile cichlids?

I am wondering what these are, I have 10 in total, a few of each in the
picture.

I want to add another 10 to 15, of a different Cichlid, hopefully which will
become colourful adults. I like the look of the Lemon Cichlid, and I also
seen a picture of a deep royal blue Cichlid, cannot recall its name.

What do you guys suggest as tank mates for these guys?

Regards,

Gary.
