Don't think the first is a socolofi, although the pics are blurry - body shape, head and colouration are wrong. I'd say its a hybrid of some kind, with some socolofi in it.
The other two pics are likewise a bit blurry but don't look like kenyi to me - again, hybrids, especially as they came out of a mixed african tank.
the white guy in the second pic - can't see his head; that orange colouration may be an albino pseudotropheus macropthalsmus though.
