My Russian is not good (=awful), but that first document has KGB written on it. The other is some kind of registration document.
I don't know about being replicas, they look fairly genuine to me - flashy cheap leatherette-ish cover and cheap paper inside, de rigeur, comrade. Wifie had half a drawer full of such documents and plastic medal boxes which we chucked out, a common fate - I did not try to stop her as she remembered those times.
