Congrats on the fish !
Hard to tell from those pics - the blotchy fellow is likely literally that, Aulonocara Orange Blotch or 'O.B.' (in the States often referred to as 'Orange Blossom' for cosmetic reasons

). He looks like a hybrid. The 'O.B.' Aulonocaras are tank bred for colour scheme and not naturally occurring in the Lake.
The barred fish in the second pic down has a touch of Lake Victoria to him as well as a lot of Aulonocara; I am thinking it is a hybrid of some sort.
The seventh down looks like an Aulonocara 'German Red' or 'Eureka' (same fish) which is a colour morph Aulonocara Jacobfreiberg and I say that mostly based on the distinct white edging on the pectoral fins...but again it is pretty impossible to tell from those pics, and it may also be a hybrid.
All of them have large dash of Haplochromine (another Lake Malawi Genus) around the nose and face, which is why I think they are hybrids.
Clearer pics would really help discuss them more accurately.
Good luck with them !
