I think you might be underplaying the possibilities here. Yes, as you say,
the nouns and titles given here are probably all referring to Yahweh. It's
difficult to think that the latest compilers of the Torah thought anything
other than that. However, Yitzhak's point is that there may be roots in
polytheistic thinking here. I suggest a look at 'Dictionary of Deities and
Demons'.
