Vali is a direct descendant of the Original Lucifer. It could be in the blood of the Lucifers that gives them multiple wings. That's why I said that I wouldn't be surprised if Rizevim also have multiple wings.

It doesn't matter whether Sirzechs is more powerful than Rizevim, he doesn't have the genes to have more than 1 pair of wings.

~Yes, Akeno got multiple wings.. multiple FALLEN ANGEL wings. Angels/FAs are different from devils. So, you cannot relate the increase of wings of the Angels/FAs and Devils.
