well first off you can pair more than one male to a female however that makes it harder to know exactly what genes the babies have when dealing with certan genes
of course you will want to pair the het pied and pied
I would pair the pewter and or the bee to the normal and the mojave to the wd
you should consider getting a few more females tho if you are searous about breeding or hold back a few that you produce
I have 16 snakes total and only 2 breeder males and 1 juvie male makes it easyier to make parings when you have more females than males
