Yes, I've pointed out that "aunt" doesn't necessarily indicate a biological relatonship; it can be applied affectionately when two have a strong bond of that nature but aren't blood relatives. (I have a few "aunts" like that! They're long-time family friends who've acted like aunts to my brothers and me. One is my mom's best friend, and thus regarded by her almost as a sister.) So is entirely possible that Cadence isn't actually related to the sisters; however, I suspect that they would have identified her as "Princess Celestia's friend" or something instead of "niece" if they didn't intend for there to be a biological relationship. But, again, that's not necessarily the case.

I also agree that Celestia and Luna aren't the only Alicorns (obviously!), and not the only royals, either. They give the impression of being the godlike queens of the entire pony world, but there may be other lands within it with different rulers. Or the royal family & bloodline could be large and long, and maybe there's a relationship between the sisters and other more distant royals.
