Guinea pigs do best in a group of two or more. You are right to get two of them at once.
It is known that they are very responsive to your feeding and handling. If you treat them well and bond with them, yes they can play with you but not the kind of playing a dog can offer. You first need a large cage. More room will make them more active. You also need to take them out of the cage and give them lots of floor time, it can make them more sociable.
Give them some toys can help too.
