It depends on what happened to the fins. If they have been bitten off by another fish, it will take time but it can regrow but if it was a fungal infection then it is unlikely to regrow at all.
To help with regrowth try using melafix or maybe put in an anti fin rot med in the water just in case.
Yes, they can under the right circumstances. For more information please view http://wiki.answers.com/Q/Do_goldfish_fins_grow_back_after_being_torn_or_eaten_by_another_fish .

how long does it take for a baby carp to grow full size
Yes, they will grow almost to half the size of their tank.
Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.
