The Hap looks like a Taiwan Reef to me. Barring is kinda poor. As for the anal fin color, that would only be seen in a male with some color. I don't know how much, if male, it would color up in that tank with rough Mbuna anyway.
#1 Melanochromis interruptus, or Melanochromis johanni poorly bred, impossible to say which.
#2 is a Lab caeruleus x Met. estherae cross
#3 agree Metriaclima callainos
#4 the barring is off for Taiwan Reef, but everything else suggests it is.... perhaps it is intimidated and showing weird markings, as it doesn't belong in with the rest of these fish. My recommendation is to move it out before it suffers.
#5 Melanochromis auratus
#6 Metriaclima zebra albino.
