2 Father's 1 egg
I know that 2 males can father the same clutch but can 2 males father a single egg?

Yes two males and two separate sperm can fertilize one egg. When you think about it female bps store sperm and as far as I know they don't pick and choose which plug to use when they mate with more than one male. If that's the case then we wouldn't have anything more than single sired clutches. During ovi if both plugs from separate males are used then it is possible for both of them to fertilize one egg. They just have to reach the egg or ovum at the same time.
It may be rare but that doesn't mean it can't happen.

I think the only time that situation can truly happen is with twins, and you end up with two babies in the same egg who had different fathers.
I don't think its possible for 2 males to actually fertilize one embryo in one egg.
Example:
A spider male and a pinstripe male bred to a normal female, and hatching an egg that's a spinner...
...I don't think so.

I'm pretty sure you're wrong, but I'm too tired to research it...

Even with twins, from what I'm reading, one sperm reaches one egg, fertilizes it, then it splits into two...

This is a basic scientific principle that applies to most, if not all, of nature. There's always a winner in the sperm race, no matter how "close" it seems. The winner is the father. The loser(s) die off.
There is no such thing as "fraternal" twins in ball pythons. For fraternal twins to occur, it's still two embryos fertilized by two different sperm. That means two different eggs, or sluggy eggs that managed to get attached. Identical twins happen as a division of one embryo to begin developing into two embryos, far more common, at least in oviparids.

ive never heared of any animal having a triploid set of chromosomes.
And thats what you would get if it would be true. Each chromosome would be present 3 times. Its not possible in any animal, its not possible in humans. If it happens anyway, the result is quickly deadly.

2 Father's 1 egg
No, its not possible.
Thats like saying 2 eggs could be fertilized by the same sperm cell. Its only one sperm per egg. After that, during meiosis, if something funky happens then it can split and form 2 babies. These would be the twins we see in bp's. The twins will be the same morph and (I'm pretty sure) sex.
Fraternal twins isn't something that really happens in bps, i don't think. Unless somehow two eggs got stuck together after they were fertilized by separate sperm cells.!
