Bees and wasps (Hymenoptera) have two pairs, flies (Diptera) one pair and a vestigal knob in the place of the 2nd pair.
Beetles (Coleoptera) have a pair of elytra, a covering for the membranous pair that they use to fly.

Actually that brings up a good point: there are wings in three distinct classes of animals (four if you count dinosaurs), these being: Insect, Avian, and Mammal (bat).
Now, it seems rather unlikely that these all evolved in serial, yet there is no common ancestor possessing wings between all of these. (Dinos are more advanced than insects, insects don’t have vertebrae, etc.)
