Press ESC to open your inventory, then at the right side of the screen where you see what is equipped to you, click the house icon above all those boxes. It will show a list of icons of all your NPCs. Whatever NPC stays out of its house, click its icon, then right-click inside the house in which you want them to move. Tip: don't do that on multiplayer mode -- I couldn't get my NPCs to do anything right on multiplayer, but they'd do what I wanted on single player.
