I did a bit of research/reading today and I think I've found an answer to some of the questions. When you decide to pop someone with leadership in the capital, the type depends on the number of turns it takes (err, vice versa). As far as I can tell, only royal side can pop courtiers (which fits the definition). That should be the tell tale sign to look for. The progression goes as follows: [edited]
courtiers, warlord, family, heir
In a royal side, family would by called prince and princess. On non-royal sides, they are called lord and lady.
Also, royalty might lose their title if they turn to a different side. They keep their royalty if they spin off a new side. I don't think we have enough data to determine if Charlie and family were royal or not. That may be one of his best kept secrets. He doesn't want anyone to know about how he lost his first kingdom, or how he attuned, or how his own daughter poisoned him.
Which reminds me. Powerful mage poisoned, dying and powerless? Become litch bent on world conquest. Sorry, got Xykon on the mind.
