identity document question

[tripleact]

I'm considering the second fish to be a poorly bred Chalinochromis brichardi, though the striping isn't always present in this species. That being said, the Melanochromis paflakelelus is a plausible ID as well. The first photo I think is a zebra hybrid, but the exact species is unclear - I've seen similar patterns in pseudotropheus hybrids before.
