No, they won’t. Two of Jupiter’s prograde moons will:

The retrograde moons and numerous retrograde moonlets may eventually crash into Jupiter, or they may be ejected from the system.

Phobos will eventually crash into Mars, Deimos probably won’t. They must have been captured by Mars, but no one has come up with the math to satisfy everyone else working on the problem.

Neptunes moon Triton is a ‘’captured moon’’ and rotates opposite to it's host, that is counter-clockwise. Which tells me, an amateur astronomer that Triton must have come from farther out in our solar system, maybe at the edge of it. And on a down note our galaxy, the Milky Way is on a collision course with the Andromeda Galaxy. As we speak we're racing towards each other at nearly 4000,000 mph. But as we're some two million, three hundred thousand light years apart, it'll be a while.
