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").
A red giant star.

A red giant star is a dying star that is in the last stages of stellar evolution. Red giant stars are red in color.
Betelgeuse is a red giant.
Polaris is a red giant star.
Polaris A is a white supergiant.

Like all stars, Polaris is made of mostly Hydrogen, but since polaris is a red giant it has a considerable ammount of Helium, as well as Carbon, Oxygen, and a number of other elements deep in it's core.
The sun is a main sequence star whereas Polaris is a super-giant.
Polaris or Alpha Ursa Minoris is actually a multi star system of 3 to 5 known stars. Polaris A is a yellowish white giant or supergiant star approx 6 solar masses in mass. Polaris Aa is yellowish white dwarf star in close association with Polaris A (18.5 AU). Polaris B is a yellowish white star about 1.5 solar masses about 2,400 AU from Pol A. All 3 stars are F type stars. A - F7Ib-II, Aa - F7 Dwarf, B - F3V There are 2 other stars thought to be associated with Polaris. Polaris C & D.
Polaris is a yellow super-giant with two smaller companions, Polaris Aa has a radius which is 46 +/- 3 times the Sun's radius.
the polaris is much larger than sun because polaris is a super giant star while sun is only a dwarf
Polaris is a Trinary star system, but there are many other trinary star systems out there, and to date no exo solar planets have been discovered around any of the stars that make up the Polaris system. Not to mention that Polaris A being a red giant and Polaris B and C being a close binary star system the existence of any planets is very unlikely.
A red giant star.
