No they don't
Roche limit innit?
Matter close to the Roche limit to the Earth don't form moons because they'd be ripped apart by tidal forces.

Ta
Though I maintain that the moon's own gravity would quite probably still disrupt the ring formation.

I don't know
How much does the moon affect satellite orbits?

Over the course of a few thousand years, I'd suspect quite a bit.
And they've already been welded together...

still possible
that they would get into some sort of status-quo like orbit where they get pulled away by the moon and then back by the earth and so on (a bit like a comet getting all the way to the asteroid belt but then getting pulled back by the sun. I'm aware there's a different reason for that, but it's still possible).
Meh, I'm sure there's a reason there aren't any rings now.

Sod it
If you're going to stick in rings, why not move the moon to somewhere where it'll not fuck with them?

Im guessing it would also
because of the the gravitational scale differences between the moon and earth than lets say compared to the gravitational forces from a gas giant sutch as saturn with a small moon sutch as Europa would only make a difference if one of the moons orbits close enough and then it would still only have a minimal desruption due to the gravitational scale difference. Because of the mass of the moon compared to that of the earth and the fact that it already affects a mass as heavy and close to the earth itself sutch as water then Im asuming the rings would be completely disrupted. OR more interesting still perhaps there would be a figure of 8 style ring system between earth and the moon (although that's doubtful as the moon doesn't rotate). If that makes any sense (not a scientist just a humble musician with a telescope)
