A lot of ways you can actually address the queen or someone from the royal family. But do these all phrases mean the exact same thing or is there a difference between them?
Maybe it depends whether the person you're talking to is actually in power now or maybe just a member of the royal family…

But it's entirely possible that Cardinals O'Malley and Wuerl, meeting casually for coffee, would address each other as Patty and Don (I don't know if they would, but there's certainly no "rule" of "English" against it).
There are too many of these rules to explain here; entire books are published as guides to correct forms of address. Moreover each realm may have specific customs related to styles and address— for example, Canada and Australia have slight differences in their official royal style and titles, even though the same person is monarch of both.
As a matter of practice, the British royal family— the de facto royal family in the English-speaking world, even in republics— actually has a guide to greeting a member of the royal family, which opens with the note
These latter include a bow or a curtsy, then
