I'm almost done with the Jupiter nama square for the current time out of retrograde August 15-30, Jupiter.

My question is for luck is it a nama material prospect or a svaha spiritual prospect?

Have I been doing the square wrong with nama?

I think both work, but in this case nama would probably be more effective since you want to affect your situation as a whole in terms of bringing you more luck. In the end both versions would likely bring you results though so no need to worry too much in this case.
