[Warhammer 40k] If Delta level psykers can read the minds of a whole town and Alpha plus can destroy planets how strong are the rest of the classes?

I wouldn't put alpha at "destroy the planet". Anyone we've seen with that power (Emperor, Magnus) would definitely be alpha+. Iota is the level where you would be co sidered a true psyker, and taken by the Imperium to be astronomical feed or sanctioned psykers. I'd put the more average Librarians and stronger sanctioned psykers at zeta-delta, capable of controlled and sustained usage of the warp on a localized scale, for example throwing witch lightning or reading minds on a battlefield, even mild precog. On the high side of Delta and beta you get the Mephistopheles and Njal Stormcallers, standouts even among Space Marine Librarians, people who can turn the tides of battle single handedly, go up against greater daemons, etc. True Alpha levels are rare as hell. One example would probably be Gideon Ravenor, who's top feat was destroying a mountain range with a burst of warp energy. Malcador was probably also an alpha level, but we see very little of his ability actually used besides the obvious sitting on the throne feat.
