Polaris A is a white supergiant.

There is no such thing as a star with a magnitude brighter than -1. Negative magnitudes indicate brighter objects, with the most negative magnitudes corresponding to the brightest objects in the sky.
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.
A magnitude 2 star is 2.5 times brighter than a magnitude 4 star because each difference in magnitude corresponds to a difference in brightness of approximately 2.5 times.
That object is easily visible with a pair of binoculars. A star's apparent brightness is exactly 100 times less than another star if its apparent magnitude is +5 greater. So, the star of magnitude 7.3 appears 100 times fainter than a star of magnitude 2.3. (Polaris is a bit brighter than magnitude 2.3).
No. Sirius is the brightest star in the night sky. Polaris is much farther down the list.
The north star, otherwise know as Polaris, is brighter than many other stars because it is much closer and perhaps larger than many other stars.
Polaris, also known as the North Star, is approximately 2,500 times brighter than the Sun. This brightness is measured in terms of absolute magnitude, where Polaris has an absolute magnitude of about -3.6, compared to the Sun's absolute magnitude of about +4.8. However, the apparent brightness of stars can vary based on their distance from Earth.
As seen from Earth, yes, Sirius is the brightest star in the night sky. In terms of actual brightness, no.
A star that is brighter than another.
Look up in the sky and you will see. Polaris is actually quite dim, compared to other stars and planets. Even at it's dimmest, Mars is brighter than Polaris.
It doesn't. A lot of stars seem larger and brighter than it. In fact, Polaris is the 49th-brightest star in the sky. To us, it is not a particularly bright star. It is important because it seems to be still as other stars rotate around it.

Because it actuall IS brighter.
The star might be closer to the Earth, or it is just brighter than the others. :D

The North Star (Polaris) does not get brighter as you travel north. It appears to be the same brightness regardless of your location on Earth. What changes is its position in the sky relative to your viewpoint as you move northward.
