The main ones are Blue, Red, Green, and Heckle, the rest are all offshoots of the others. Heckles are a seperate specie.
 
I meant brown instead of red, sorry :).

Yes, most are results of crosses between greens, blues, and browns and different color morphs of the same strain. Some are hybrids between these 3 and heckels. There are some variations between heckels too.
 
Sure,

green (this one happens to be a tefe)

No, it's just a variation of the green.
