Can anyone identify these guppies?

Hi,
I got interested in cross breeding guppies from my pond in a tank to create new strains.I have 2 males and i can't find out what breed they are.The first one i think is a yellow snakeskin guppy but I'm not sure.The second one is less that 2cm in length and i cannot identify him.

The second one looks almost like an endler hybrid
