Sometimes other NPCs will take an empty room that you have made for another new NPC. If this is not the case and you do have room that NPCs haven't already taken, then you will have to wait a day in Terraria. That's exactly what happened for all of my other NPCs to arrive. Even when I got my first musket and got an arms dealer.
