Is it possible for a planet to have multiple moons in a nearly stationary orbit?

Anyway, what you're describing is more or less possible, with some caveats. A major question is that of stability - how long those configurations remain in place.

There are several notions you need to think about:

Geostationary orbit: it's the orbit where satellites have an orbital period equal to the planet's rotational period, so they appear stationary in the sky.

Roche limit: the lowest orbit where natural satellites remain in one piece. Any lower than that and they break up into pieces due to tidal forces.

Hill sphere: is the region where the planet's attraction dominates and satellite orbits remain stable (as opposed to being stolen by the star, etc).

Usually Roche limit &lt; Geostationary orbit &lt; Hill sphere.

Satellites at the geostationary orbit appear fixed. Those close to the geostationary orbit would indeed appear to move extremely slowly across the sky. Orbits higher than geostationary would appear to move backwards.

With regards to the long-term stability of multiple moons in various orbits, they would be stable if the orbits are far enough from each other, or if they're sitting in each other's Lagrange points. Also see here https://worldbuilding.stackexchange.com/questions/36929/stability-of-multiple-moons
