If you could ask Ra any one question, what would you ask?

As far as Ra's we-ness vs one-ness, I think the trick is realizing that it's both at the same time. Both are true, just depending on what perspective one is looking from. Ra-the-Personality is a singular entity created out of the energetic interactions of the various entities that make up Ra's social memory complex. But each of those sub-entities is still separate and distinct as well, simultaneously being themselves as well as contributing to the gestalt overmind.

It's sort of like our relationship to our own bodies. A person's liver is, from one point of view, a separate object from the person themselves. That liver has very specific functions and duties which the person couldn't otherwise replicate without it. (And they wouldn't have too much time to try.) Or the various micro-organisms that call our bodies home. A person's gut bacteria are "part of them" from one standpoint, yet from the POV of the bacteria themselves, they're separate singular organisms trying to live their teeny lives as best they can. Their lives just happen to be lived in a body-world whose continued wellbeing they help ensure, without ever being aware of it.

That's why Ra says there's no distinction between singular and plural when talking about him\them. He is both.
