Yes. There are a number of binary stars scattered about the sky, and there is always one visible at night (unless it is cloudy!)
In the northern hemisphere, one of the most famous "visual binary" stars - two stars that appear to be next to each other, but which are not gravitationally bound - are the middle "star" in the handle of the Big Dipper. They are Mizar and Alcor. In Roman times, the Legions used these as an eye test; if you could see two stars, then your vision was good enough to be an archer. If you only saw one, then it was not.
The star Mizar itself is a true "double star"; two stars orbiting their common center of gravity.
Anywhere north of 30 degrees north latitude, these stars (and the Big Dipper itself) are circumpolar; they never set.

Why are constellations seen all year?

Why does the sun change its altitude in the sky over a year but the stars do not?
Because we are revolving around the sun, but not other stars. Edit: and the stars (i guess you means constellations?) do change their positions, they're just so far away you can't notice it. What you can notice is that the constellations "move" with the seasons, because our planet's axel is tilted and when it revolves around our star our point of view is changed.
