Id Help - Malawi Haps/peacocks

[ChiefBrody]

I'll do them one at a time. This is Denim. He was silver/white barred when I got him, but now he's this gorgeous boy. Is he an Ahli?
This is Boris - no one knew what he was at the store, but I thought he looked like a red fin borleyi, so I snatched him up. Now, I'm not so sure. Is he really a she? He's got some color now so I'm a bit lost, lol.
Another pic of Boris

ETA: A pic of Denim, about a month after I got him.

This is Domo, who was sold to me as a Fireline Mloto, but I'm not so sure. What do you guys think he is?
Darn it... the "before" pic of Denim didn't attach to my 2nd post. Here it is again.

Anyone?

Pic 1 is s.fryeri. pic 2&3 are are a protomelas, probably red empress. Pic 4 is some sort of capidochromis. 5 is a peacock, would need a better pic and it to have more color to be sure of which species.
