The Big Dipper, or Ursa Major has two stars (sometimes called the pointer stars) which line up directly with Polaris. Those two stars, at the "lip" edge of the Big Dipper, are Dubhe and Merak. Merak is at the "bottom" of the Big Dipper, and Dubhe is right at the "lip".
No single star points towards Polaris.
North star also called Polaris
Polaris is the north star.
The constellation points to the pole star (Polaris).
The Northern Star is also known as Polaris. This is the star that the Earth's axis of rotation approximately points to.
The pole star (Polaris) is not constant. The Earth's precession creates a continually varying point in space where the North Pole points. Right now, it is within a degree of Polaris, but there is a 26,000 year period where Polaris will not always be the pole star.
The asterism known as the Big Dipper, visible in the Northen Hemisphere and part of the Ursa Major constellation, has two stars which famously point approximately at Polaris. (The stars are Merak and Dubhe.)
Currently the Earth's pole points toward Polaris in Ursa Minor. 5000 years ago it pointed towards Vega.

The last 2 stars in the cup portion points up to the North Star of Polaris
It should be located as close to possible above the North Pole so that is points North.
The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.
