The constellations along or near the ecliptic, including the constellations of the Zodiac, are visible from most of north and south america. At high latitudes in either direction, the equatorial constellations will be pretty low on the horizon and may not be visible unless the terrain is fairly flat, or from high elevations such as mountain peaks.
Many. Here is a list for you. http://www.astromax.com/con-page/con-sth.htm
The constellations near the plane of the ecliptic (the zodiacal constellations) are only visible at certain times of the year. The constellations towards the poles (N and S) are visible at all times of the year from their respective hemispheres. In the South, the Southern Cross would be one example and in the North the Great Bear (or plough) would be another.
Polaris, or the North Star, is always visible in the Northern Hemisphere. The entire sky rotates around it during the night. The Big and Little Dipper aka Big and Little Bear are visible, as Polaris is a part of the Little Dipper. Draco, Casseopia, and Capheus are also formations normally visible around the North Star. The other constellations vary with the seasons, see the star chart referenced.
It's only visible at night, but it is visible all year round in North America. In fact, it never goes below the horizon anywhere north of the equator.
There are completely different constellations on South sky. Behind the equator there is no Northern star visible.
Depends where you live.
Half of all constellations are visible from the north pole, andall of them are visible from one inch north of the equator.

The Big Dipper and the Ursa Major are the most visible constellations from NJ. The May constellations that contains over 200 galaxies is also one of the most visible constellations from NJ.
Lots of constellations are visible during the winter months. About half of the constellations are above the horizon, and therefore usually visible, at any given moment. What constellations are visible would also depend on whether you live north or south of the equator (this affects the definition of "winter"), on the specific month, and the time of night.
Circumpolar constellations are visible all year long, depending on where you are viewing them from. At the north pole, or the south pole, some constellations are visible year-round, these are the circumpolar constellations. On the equator, there are no circumpolar constellations because of the earths rotation, that is why circumpolar constellations are at the "poles". Some of the circumpolar constellations can also be viewed from other parts of the same hemisphere, such as the big dipper and the little dipper, although they are circumpolar, they are also seen in other parts of the northern hemisphere. Circumpolar constellations in the northern hemisphere, will never be seen at the south pole, and vice versa. I hope this helped.

Some of them, yes. Constellations along the Zodiac can be seen from either hemisphere, but constellations well away from the celesial equator cannot be seen very far in the other hemisphere. For example, Ursa Major is not visible in Australia, and the Southern Cross is not visible in Europe or North America. Most of the "official" constellations were named by northern hemisphere astronomers, or European navigators sailing in southern waters. Look at how many southern hemisphere constellations have a nautical theme; the Telescope, the Octant, the Quadrant. Even Cetus, the Whale, was named by sailors, not people who LIVED there.
These are called circumpolar constellations.
