No. Normally, two lines will uniquely identify a plane, unless they happen to be parallel. If you add a third line, it will usually not be in the same plane.

Not quite. Two lines that meet will uniquely identify a plane. But you can have lines that are neither coplanar nor parallel.

For example, consider a cube and think of the line defined by the front bottom and one of the back verticals. Neither parallel, nor coplanar.
