Couldn't find anything on FOUR SHALL DIE. It's interesting to note that a young Dorothy Dandridge stars opposite Mantan in that one, but because it's a Million Dollar Production, it may have scattered to the four winds.

I don't see any holdings for MR. SMITH GOES GHOST or COMES MIDNIGHT, either, but all three films might be out there in 16mm.
I think FOUR SHALL DIE has shown at Dandridge film festivals, so there's probably 16s to be had, at least of that title.
