Do you have all the houses built for them correctly? You can use the Housing Query option to check if a house is suitable or not. It must be at least 10x6, have a table and chair (Flat Surface and Comfort item), and an entrance (You CAN use wood platforms, but make sure they aren't in the centre of the house; at night, NPC's must stand on a solid block, and they stand in the centre. Wooden Platforms are not a solid block. Trying to do this will result in the home being called "Suitable", both from the query and trying to move an NPC banner inside).

If this doesn't work, read a little more on Homes. Good luck!
