Well, Kiba, Kubikiribocho and Samehada were returned by Kakashi, Killer B and in the anime, Omoi, in order to further consolidate the alliance between the 5 villages. As for the other four, Hiramekarei was in Chojuro's possession and the other 3, Nuibari, Shibuki and Kabutowari, were probably unsealed after the war and given to the Mist.
