Two are enough, if not coplanar.
Yes
The North Star is not in the Big Dipper. It is actually Polaris, which is located close to the handle of the Little Dipper constellation. The Big Dipper is useful for finding Polaris because it points towards it.
Polaris or Alpha Ursa Minoris is actually a multi star system of 3 to 5 known stars. Polaris A is a yellowish white giant or supergiant star approx 6 solar masses in mass. Polaris Aa is yellowish white dwarf star in close association with Polaris A (18.5 AU). Polaris B is a yellowish white star about 1.5 solar masses about 2,400 AU from Pol A. All 3 stars are F type stars. A - F7Ib-II, Aa - F7 Dwarf, B - F3V There are 2 other stars thought to be associated with Polaris. Polaris C & D.
