21. Can someone retain copyright of their work even if they no longer physically possess the originals of their work?

Yes, ownership of copyright in a work is different from the ownership of the physical material in which the copyright work is contained.  As such, the transfer of title of the originals of the work does not transfer the title to the copyright thereof and the author can retain the copyright in the work.
