All of them orbit a planet.
All of them would be deemed stable.
Size doesn't matter.
So all of them are essentially moons under the current 'definition'.
I suspect a new one will be made soon ala Drawf planets to exclude a lot of these recently found moons.

I see to recall a lot of conjecture about Phobos and Deimos, Mars two companions… Phobos (I think…) is potato shaped and as such (ie not spherical) was theorized as potentially being a captured passing space rock and therefore not a Moon (Earth like) but merely a moon in orbit.
