(Astronomy) If the sun will eventually turn into a red dwarf and expand, will the orbits of the planets change?

Yes. The sun will lose a significant amount of mass, which will mean the planets would orbit slower and further out. But there will also be air resistance from all that solar wind, which will keep them from going out too far. They'll still orbit slower. And several of the planets will end up inside the sun, where the'll slow down and fall toward the center.
