No doubt about Silver, but then he was neither a Dmeon nor alive to begin with.

But please tell me in which chapter do we see Franmalth "dying"? Because all I remember is him being shown as a Mushroom and then disappearing from the story.

With Mard only being killed when his book was burned, I think there is the possibility that the "dead" Demons, save for Mard (who's book was burned) and Kyouka (Mard was pretty clear about her dying for good from linking with Face) might have been returned into their books and thus could theoretically be brought back.
