Polaris does have apparent movement, but it is slight. Now, the angular distance of Polaris to true north is less than 1 degree). So, the other stars appear to be rotating around Polaris as the earth rotates throught he night.
However, the earth wobbles around its rotational axis, resulting in true celestial north moving in an orbit on the celestial sphere enveloping the earth. The center of this orbital cirrcle is called the earth's true ecliptic north pole. Basically, the true celestial north moves in this cricle, crossing very close to Polaris and then about halfway through the circle crossing close to Vega.
If you happen to be around in about 12,500 years, look north. Vega will be the North Star. To the naked eye, it's apparent movement might be noticeable. I'll let you know if I see it.

Is Polaris A a Red Giant?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
