Do the planets of The Milky Way all move in one plane?
On pictures and simulations of The Milky Way, the planets all seem to move in the same plane. Is this actually the case, or do they move at different angles to the sun's poles (if the sun has poles)?

The eight planets within OUR solar system are aligned more or less (though not exactly) on the same plane. The orbits of all eight of them are aligned with the sun's equator within about 7 degrees. This means our solar system is more or less "disk shaped," at least as far as our local planets and asteroids are concerned. (Comets are a different matter; they're all over the map.)
But If you're talking about the whole milky way galaxy (not just our solar system), it's a different matter. The milky way has its own "disk" which is aligned completely differently than the disk of our solar system. Furthermore, other solar systems within the milky way have their own disks that are randomly oriented compared to our solar system's disk and the milky way's disk.

No. The planetary systems of other stars are oriented in many different planes, depending on the history of their particular star.
