Only 10% of the world have magical power the rest doesn't. Not everyone can use magic because not everyone posses the most important thing to use magic which is magic power(reserves). I don't think Juvia was born with her magic I think she learned her magic because she was influenced by the fact it always rained when she was around.

On the learning more than 1 magic thing I couldn't agree more. A mage can learn any type of magic they please and any amount as they please but there are conditions. 1. You need the magical reserves to support you type of magics. 2. You magics most fit you well. You don't want to have Erza's magic and posses no combat skills. etc.
