As always, it depends. They can really get along sometimes (however this is rare), and sometimes fights can break out. I recommend getting multiple of the same gender, but if you get different genders, you should only get 1 male and 1 female, because fights can arise for many reasons between the males and females, especially when they mate. I hope this answers your question.
If you mean keep them together....yes, but I wouldn't recommend mixing sexes. The male will get both females pregnant. If you are interested in breeding (be aware, every time you breed there is a 1 in 5 chance the females will die) make sure you separate the pregnant females from the male before they give birth, as they can get pregnant again in as little as 2 hours, and back-to-back pregnancies are very hard on a guinea pig. If your male is neutered, it is okay to put them back together a month (approx, check this online) after the procedure.
Keep them with a male guinea pig. Be careful because sometime the male with harrass the female.
Your male guinea pig is trying to mate with your female guinea pig.
Yes and fast
you shoudl not put a hamster and a guinea pig in the same cage no matter what.
The male guinea pig is called a boar and the female is a sow because of their name "pig", even though they're not pigs. A male pig is a boar and a female pig is a sow, so the guinea-pigs have been named after them.
No. There must be a male and a female for the guinea pigs to have offspring.

A male guinea pig can impregnate a female when it's only two months old. It should be separated from its mother and sisters by six weeks.
