Tankmates for my 55g???

[jah29]

So I'm in the process of buying fish for my tank. Below are some pics of it. I need some advice.

size: 55g
temp: 78 F
pH: 8.2
NH3: 0
NO2/NO3: 0
Current Stock list:
- 1 : Pseudotropheus crabro : Bumblebee cichlid
- 1 : Pseudotropheus demasoni : Damanson's cichlid
- 1 : Pseudotropheus lombardoi : Kenyi cichlid
- 1 : Pseudotropheus estherae : Red Zebra cichlid
- 1 : Labidochromis caeruleus : Electric Yellow cichlid
- 1 : Maylandia greshakei : Ice Blue Zebra cichlid
- 1 : Hemichromis bimaculatus : Jewel cichlid
- 1 : Aulonocara Hybrid : OB Peacock cichlid Hybrid
- 4 : Corydoras paleatus : Peppered Cory cat
(the Kenyi cichlid is a female, the rest are males as far as I know)
(all the cichlids are currently 1.5-2.5 inches, with the OB Peacock being the largest and the Alpha male of the tank)

How many more African cichlids could I fit in this tank?
What are some good choices of cichlids that would coincide well with the current fish?

Thanks
