Yes, they do. Why? Because they can't remain static forever. Assuming they were ever static (motionless) with relation to one another (an assumption that is NOT true), they would start to move, eventually, due to their gravitatioal force on one another.
They dont move.
Fault.
It allows the continents to move relative to each other.
The plates move relative to each other in varying speeds. The Pacific plate moves against the North American plate at 5 cm/yr. The Arctic Ridge has the slowest rate at less than 2.5 cm/yr., while the East Pacific Rise has the fastest rate at more than 15 cm/yr.
The fracture along blocks of crust (tectonic plates) is called a "fault" or "fault line".
Stars all appear to revolve around the sky each day as the Earth revolves, but relative to each other the stars stay 'fixed'. That is because they are so distant it takes years for any of them to move appreciably.
They dont move.

Two parts that are joined, but can move relative to each other.
the large sections of the earth's crust that move relative to each other
It consist of large sections called tectonic plates, which move relative to each other.
No, they are not. They are in lines of sight which are close to each other and they are all so far away that they do not appear to move very much relative to one another. But in most constellations some stars are likely to by hundreds, if not millions, of times as far away than the nearest stars.
Friction. When they move it is dynamic friction. If they are not moving relative to each other then it is static friction.
