Yellow with black fins = yellow labs. They're in a few of your shots. Nearly impossible to sex by looking at them.
Orange/peach = red zebras. Again, in a couple of the shots. Peach SOMETIMES indicates males, but yours look too small to have undergone a color shift, so it could just be a different strain.
Yellow/white with black stripe = auratus. Juvenile, so too early to tell if it's male. If it is, it'll turn colors.
Need a better pic of the ones with the red/orange dorsal fins to tell what they are.
First appears to be some type of cynotilapia... I think?
What size tank is this? That auratus is going to get really brutally mean shortly. The red zebras will crossbreed with the yellow labs. Just a heads up.
