I would go with less species and larger group sizes, say 5 species max, and 6-8 of each species.
If you're interested in breeding at all, I wouldn't house the M. callainos and estherae together, or the estherae and Yellow labs.
You definitely want more than 3 Yellow labs in order to make them feel comfortable enough to behave normally. They tend to be easily stressed in smaller groups.
There could be some friction between saulosi males and the Cobue males. I don't think they'd crossbreed, but the boys might not take too well to each other.
I'd prefer the fainziberi, too, and if you reduce your species numbers to 5 groups, I think you could include them as one of your species. Stunning fish.
Here would be my picks from what you've got for 5 species:
M. callainos 6 (preferably just one very happy male)
Yellow labs 8 (male/female ratio won't be important)
Ps. flavus 4-5 (females are drab, wouldn't want alot of those)
M. cyaneorhabdos 6-8
M. fainziberi 6
The petricolas would just be icing on the cake!
