King Snake Breeding Questions.

So I have breed ball pythons and such even corn snakes, but I got a lot of king snakes and i have no idea how to go about selecting morphs and such.

I have a male striped albino king snake. I have a female goins king snake. I have a male brooks king snake.

So here is my questions.

1. Are these morphs or different species entirely?
2. Can I breed any of them?
3. What would the hatch-lings be for each pair?
4. How old/heavy should a king snake be before breeding? (male and Female)
5. Are there any tips/tricks specific for king snakes?

Nobody can help me?
