You will notice that the male guppy has a long pointed anal fin. They use this to transfer sperm to the female guppy via the gonopore (hence the constant chasing). The dark spot on the female is called the gravid spot, it is the eyes of developing fry. Females have the ability to carry viable sperm for up to six months and the only chance a male has of continuing his DNA is to catch a female within a day of her giving birth.

Simple answer is yes. Guppies mate and produce young under almost any reasonable conditions. The presence of other fish will not bother them at all provided the other fish are not predators and the guppies under pressure for survival.
No, they are to different types of fish and it would be impossible to breed them.

Yes and it happens all the time. That is why it is very hard to get well bred guppies nowadays.
