Not an answer to the aspect ratio question, but just an FYI for those interested:  Alpha DVD offered the films as stand-alones (three of which are included in their three Retro Science Fiction boxed sets that are still available at their website), and Something Weird Video/Image offered the four films as two double feature DVDs.  (The SWV versions I still see turn up on Amazon.)  As August points out, the SWV included his excellent look at the Starman saga.  (And those are the best-looking versions of the films I've seen.)
