I'm curious about this:

Let's say I'm flying in an airport with multiple lounges and I'm flying with 3 other people without status.

Can I use *G, United Club card, and Priority Pass all in one go?

At the same lounges? At different lounges? Or if I'm flying F/C?

I know United Club gives me two guest, but from what I understand that only applies to the United lounge and I am limited to one guest in other *A lounges.
Priority Pass is sometimes accepted. *G I can bring one guest and as with F/C ticket.
