how many magic fruits are there or is it a mystery
is the goal of most pirates to find them
do people sell them if they get a second or give it to friends or what
I don't think Oda ever gave a ceiling for devil fruits.
Most pirates want to become rich and unquestioned. A lot want to find Gol D. Roger's treasure. Super powers usually help for that stuff, especially since most people they fight also have them. Doflamingo wants to murder a bunch of people, so that really helped his goal!
People usually sell them. There was a situation recently where (I'll keep it vague)
Luffy was trying to win a devil fruit for personal reasons because he didn't want anyone else to have it, but then had to leave and let his friend take his place to win and subsequently eat the fruit.
