NPCs will respawn as long as you have a suitable housing available. NPCs won't respawn at night and they also won't spawn if you have a goblin invasion/frost legion somewhere in your world. Try to get him to spawn. If he absolutely won't and you're doing all these things, then it must be some kind of bug. In which case I'd say probably just make a new world.
