Weapons Plaques? Or Weapon Racks? You can interact with the Racks, but if there is a weapon already on the wall, that is not a Rack. The racks you can put weapons in should be empty when you buy the house. Also, you have to have the weapon you want to put on the rack equipped or it will not go to the rack when you activate it.
As for the Mannequins, they do go invisible when you first put stuff on them, but they reappear after a moment.
