[Tolkein] Are there many people in Middle Earth who are "in the know" about Gandalf?

He tries to pass himself off as a wise old man, and maybe he can explain away his magic sometimes, but various kings must know he was advising their grandfathers when they were children and hasn't aged a day. Does anyone know the full extent of what he is, and if not, what do they *think* he is?

Just about every king, court official, and other important person seems to know exactly who he is.  They may not know the full extent of his power, but they know he's a wizard and he's been around for far longer than he should be and that he's knows a lot more than he's saying.

The common folk don't know any of this, however.  To them, he's just some old guy.
