Okay, if I remember this correctly...Lint is an Extra Joker Candidate. This indeed suggests that there is a current individual who fills the official "position" of Extra Joker, while she is merely a potential replacement. Mind you, this likely has nothing to do with the Brave Saints reincarnation system: she was likely reincarnated with a Joker card but gained the unique trait of silver wings that places her on the list of Extra Joker Candidates. However, who the current Extra Joker is has not been revealed. As for whether Heaven has more Jokers, the answer is a tentative "yes" that there is most likely more Jokers out there. Even if there aren't, there should be Joker cards available to use should they come across someone who fulfills their criteria for one. That being said, this is merely speculation based on what is known, Ishibumi himself has mentioned nothing about the current number of Jokers (or rather Joker Candidates, assuming that there is only one "official" Joker and one "official" Extra Joker) in the Brave Saints.
