Parallel lines
They are parallel lines
Yes - if they are straight lines.
Skew lines. However, it you alter the plane(s) these two lines can become parallel.
no
Intersecting lines.
They are called skew lines.

If they are not parallel and do not intersect then they would not be in the same plane (not possible), but they would be called skew lines.
They are coplanar.
Two lines that are in the same plane and never intersect are called "Parallel," meaning that they are lines with the same slope, but not y-intersect.
If the two lines lie in the same plane, and they do not intersect, then they are parallel. If they are not in the same plane, and do not intersect, then they are called skew lines.
