Yeah, there are 500 gifters.
And same as above, there is a distinction made between the Gifters and the Headliners. Gifters as those “Blessed with powers,” and Headliners as “The chosen Gifters.”
As to how many Headliners? As many as there are card names, I would assume. Following the naming scheme.
I hope we get to see more “normal” looking headliners because in Sheepshead’s Vivre card it says that he mastered his smile fruit. Meaning that there are levels to mastery.
Hopefully that means that Momo can master his artificial fruit. Although there might be some inherent differences between Momo’s fruit and the smile, because Momo’s fruit was made by Vegapunk in contrast to Caesar’s faulty smile. Vegapunk’s fruit was considered a failure by the man himself but one of Punk’s failures is still better then Caesar’s creations. Similar to how I assume the Numbers are Punk’s creations vs Caesar’s failed attempt with the children.
I also hope to see some strong Pleasures. Unlucky suckers that got the short end of the smile gamble, but still strong. Just laughing away.
