If a super massive planet and two stars orbit each other in the center of a star system, all the planets that orbit those stars are moons then technically, right?
This is all super fuzzy and completely arbitrary. These concepts are constructs. Humans could make them better. Instead, everyone decided to make it all worse.
Satellites? Natural or manmade, small or big, doesn't matter.
At present, purely theoretical: we don’t know of any. They are probably quite rare, but we don’t really know - maybe, in centuries to come, we’ll know of dozens of examples; maybe, there are none to find in this entire galaxy
