Yes. If he can catch them and swallow them he will. If you wish to keep and rear a few guppy fry then you should use a spare aquarium and have no fish in it except for the gravid female. Once she has had the young she should be removed too because she also will eat the fry. The babies(fry Whatever) will be hard to remove, so put the pregnant female in a tank that you want for the fry. good luck!
Don't mix them.The male and female guppy will devour all the fry they can get!
Put one male together with three females. Provide hiding spaces for the fry.
Many male guppies have 'black spots' but if by "black spot" you mean "gravid spot" then no, a male guppy can not be 'gravid' because gravid is the equivalent of "pregnant" and male guppies can not get pregnant.

Yes, because guppies will eat their newborn fry.
This happens all the time. Female guppies can have a succession of litters after just one mating. You may see new fry several months after buying her from the pet store.
