The Nova mount may be the Praktica Nova mount which is probably a screw mount, aka M42. The photos do not show the mount to verify.
I take it you haven't actually seen these lenses. The Sigma has no contact points so is manual focus and aperture. It might be a Pentax K mount but you probably want to verify that somehow.

It's not Pentax, it's a Konica mount. You can verify it by looking through a web page that shows what most mounts look like.

If it were possible, I really don't think you want to bother anyway.
