What devil fruits and their users that are able to fly? In the Alabasta Arc, Pell said that there are only 5 known flying devil fruits.




  Pell: You're lucky to see this. Only five flying devil fruits are known to exist


What are these "5 known flying devil fruits" and who are their current users? 

Apart from the 5 known, did they discover new flying devil fruits?

Note: I'm only talking about the "real flying devil fruit". What I mean here by "real" is like Pel who can naturally fly unlike others who uses their creativity in order to "fly", example of this is 


   Doflamingo.
Nope, there are more than 5 DF users who can fly:


Doflamingo, who can fly using his DF by attaching his thread to a cloud

Shiki, who had a DF called Fuwa Fuwa no Mi 
Sabo
