Yes.
If your cat has been outside while she has been in heat, she has mated. Keep her inside until her heat period has passed. One kitten is produced per mating. Cat gestation is roughly 9 weeks.
You can't tell except by watching them mate. If the female is in heat and there are many males around it is most likely one if not more have mated with her.
Sandstorm, because she mated with firestar
Only if she mated successfully whilst in heat.
2 or more.
If you have a boy cat, that probably means that she has mated with your cat.
As innocent as you think your kitty is, it is impossible for a cat to conceive without intercourse.

You can't. A cat will continue to come into to heat until it is mated (then will be back in season as soon as the kittens are weaned) or spayed. Due to the greatly reduced risk of many health problems such as cancer in a spayed animal (not to mention spraying around the house and desperately trying to escape outside), spaying a cat is highly recommended.
