Supreme Power Squadron Supreme had one iteration and they said the Nighthawk that survived in Secret Wars would join the Squadron Supreme in the main universe and thats the same Nighthawk so yes they are the same, same with Blur he is from New Universe he didn't appear in Squadron Sinister yet(and I assume won't at this point) but he is also surviving Secret Wars.

I agree with Annabelle also I said so in my post, I'm talking specifically of those characters, the other domains it makes perfect sense.
