You should do nothing. This behavior is normal and doesn't affect anything.

Look at the color or pattern on your guinea pigs fur, or see its personality.
Yes, guinea pigs must mate to produce offspring.
well guinea pigs will mate and make themselves but its really just called nature
Sometimes girls pee on boys if the boy is trying to mate with her and she doesn't want him to. If the guinea pigs are the same gender then one could be annoying the other.
Sometimes rabbits will try and mate with guinea pigs no matter what sex they are. However the rabbit cannot impregnate the guinea pig because it is a different species.
Guinea pigs wobble because they are bored and are trying to entertain themselves.
Yes, they will if allowed to.
Just as much as humans.
Rabbits can not mate with guinea pigs. If the rabbit tries to mate with a guinea pig, it means that:They shouldn't live together. Rabbits and guinea pigs shouldn't share a cage because rabbits get easily scared and can accidentally hurt the piggies.Your rabbit could be trying to show dominance but again, give each one its own cage. A rabbit trying to be dominant could hurt the guinea pig.You should separate them when the rabbit mounts the guinea pig. Otherwise, if they get along, they can be together when you're there to supervise, but never when they're alone.
I would. But if you are not for sure, then call a vet and see what they say.
