Guinea pigs are living, breathing animals. They are not toys or objects solely for your amusement. They need good food, a good environment, and good handling. They get lonely and bored when kept by themselves, and live awful lives in small cages that pet stores sell.
You have two males and one female, are you planning to breed? Breeding is very dangerous for guinea pigs, and many time is fatal for both mother and pups. Judging by your previous posts, you do not know much about guinea pigs, so I strongly advise you
not to breed them.
Just because your female guinea pig has lived in the same size small cage her entire life does
not justify the fact that she is living her life in an environment that is much to small. A bigger cage (minimum of a 3x2) would be great for her. She needs the space, she needs to be able to run around to be happy. Pet store cages simply do not offer that. The proper amount of space to run around is essential, and holding her/lap time does not count as exercise or floor time.
She needs a female companion, to keep her company. Guinea pigs should not be kept singly as they are social by nature and are much much happier when in a least a pair.
It sounds to me like you purchased your guinea pigs (I assume you got them from a pet store....) without knowing too much about them, so you did not know what to expect when you actually got them home.
Guinea pigs are not toys.
