Two lines that will never meet are parallel lines. Parallel lines are two lines that are always the same distance apart and will never intersect, no matter how far they are extended. This property is a fundamental concept in geometry and is defined by having the same slope but different y-intercepts.

No. Skew lines are never coplanar. Stand in a cuboid room and consider the line where the opposite wall and the floor meet. Consider also the line where the walls behind you and to your right meet. Those two lines are not coplanar.
