I believe the normal rule is 4 species in a 4' tank
each male will want to take up about 1 sqft of floor space. So you have room for 4 males. You already have multiples of 3 species. I understand the desire for the extra mainganos, I recently starting stocking them too.
at this point you need to pick what you want to go with. I had 7 or 8 species in my 6' 125 and ended up with a few fish in the corners, etc. not good.
I would drop the bees, they get aggressive and BIG.
Get more mainganos and some cynotilapia afra 'hara' if you want some pretty 'white' males. the females will look like your cobalts, so I would drop those instead and get a 2 males and 6 or 7 females.
just an idea.
