What is the largest circle that you can draw around Polaris without running into the horizon?

It's the circle whose radius is the same as your north latitude. (That means it depends on where you are, and if you're south of the equator, Polaris is below your horizon anyway and there is no such circle.)


What is the altitude of Polaris as seen from New York City if the terrestrial coordinates are 41 degrees north 74 degrees west?

Polaris makes a little circle of about 1/3° radius around the celestial north pole every day. But we don't notice that, and it appears to mark the pole itself. So the altitude of Polaris is essentially equal to the observer's north latitude. If he's standing 41° north of the equator, then he'll see Polaris at roughly 41° above his northern horizon.

Is a red giant a polaris?

No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
