it could take decades to list them all (as there have been hundreds, maybe thousands, along with different varieties) so i will simply say that you might want to check out star wars collector sites, such as BryansToys.
if you mean what are the names of the action figure series', then the most prominent ones are the original Star Wars, Empire Strikes Back, Return Of the Jedi, Power Of The Force, Power Of The Force 2, Phantom Menace, Attack Of The Clones, Clone Wars (original), The Complete Saga, Revenge Of The Sith, The Force Unleashed, and The Clone Wars (new animated movie and t.v. series)
