False. Think of a corner of a cube such as a room. If you face the corner, there is one line defined by the floor and the wall to your left. A second line defined by the floor and wall to your right and the third line, going vertically, defined by the two walls. These three lines are mutually perpendicualr (or orthogonal) - very definitely not coplanar.

Not necessarily. The Tropic of Cancer, and the Tropic of Capricorn, imaginary lines on the surface of the earth (an approximate sphere), are parallel but they are not coplanar. You could draw similar lnes on a proper sphere that were parallel but not coplanar.
Yes. Parallel Lines are also two coplanar lines that do not intersect.
