If the first Guinea pig is either female, or a neutered boar (male), then they should be fine. They thrive much better with company than on their own.
In my experience, the perfect realtionship is a neutered boar and two females.
The cage should be as big as possible however 3 piggies should be fine in a cage 600x1200mm as long as there is a bit of room for them to plan and jump.
I have a cage that is two storeys, one for a big play area and then a slope up to a second floor where all their bedding is.

depends on the colour and personality
Yes!
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.
Well if it is a male, it is possibly fighting over a female Guinea hen Or if it is both female then it should be my theory switched with the genders
About 950g
depends if its a male or female. if its male, 1.5-2.0 lbs. if its a female it should weigh 1.0-1.5 lbs. my guinea pig weighs 3 lbs, and its female :)
it really depends on the guinea pig, some get along fine with friends some don't
Guinea pigs are rodents. They can breed early in life. As pets they should be limited to only about 5 litters a year.
if a female guinea pig is biting the other one separate them. Then put them back together when the one got bit is ok again!!!
Female guinea pigs usually don't have babies until they are about 4 months old.
at the second female trimester
