No. The North Star, also called Polaris, is a star that is almost directly above the north pole. The zenith is the highest point an object reaches in the sky.
Less than a degree from the zenith.
Near the zenith, i.e., the highest point in the sky.
That's the observer's 'zenith'. Since it's referenced to the "observer's head", each observer has a different zenith.
If you were standing at Earth's North Pole, the North Star, also known as Polaris, would be located directly in the zenith, or straight overhead. This is because Polaris is situated very close to the celestial north pole in the night sky.
The star closest to the zenith depends on your location and the current time, as the location of stars in the sky changes throughout the night and with your position on Earth. The star that is currently at the zenith will be the one directly overhead in your local sky.
57.5 degrees north of your zenith.
Less than a degree from the zenith.
Near the zenith, i.e., the highest point in the sky.
If you are at a location with a latitude of 10 degrees north, a star with a declination of 10 degrees would be located directly overhead, at your zenith. This means the star is in the same plane as your latitude, making it the highest point in the sky relative to your position.
If you're standing exactly on the north Pole, then during the six months when the sun never rises, Polaris ... the "Pole" star or "North" star ... makes a tiny circle directly over your head once a day, about 1/3 of a degree from the North Celestial Pole. Everything else in the sky circles the same point once a day, but in much larger circles.
It is called Zenith.

Polaris, otherwise known as the pole star or the north star, is very close to being straight up from the north pole. If you were standing right at the north pole, Polaris would be almost exactly at your zenith-- straight up.
The North star will be 75 degrees above the horizon. Whatever degree you are at latitude, the North star will be the same degrees up. So at the north pole (90 degrees north), the star will be at the zenith (straight up). While at the equator (0 degrees north) the star will be at the horizon.
No. It will only always be CLOSE to the zenith if you happen to be at the north pole. At other latitudes, for example if you live at 30° north latitude, it will be about 30° above the horizon (to the north), if you live at 50° north latitude, it will be about 50° above the horizon, etc.
