If lines lie in two planes, then the lines are coplanar.
Parallel Lines - Skew lines are lines that do not intersect and do not lie in the same plane. If two lines lie in the same plane they they must either intersect or they are parallel.
Parallel Lines.
In a Euclidean plane (the one which we are all familiar with), they would be parallel lines.
They are lines or points that lie on the same plane. Remember 3 or more points are collinear if they lie on the same line. IF those lines lie on the same plane they are coplanar.
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
Skew lines cannot lie in the same plane.
If lines lie in two planes, then the lines are coplanar.
Parallel Lines - Skew lines are lines that do not intersect and do not lie in the same plane. If two lines lie in the same plane they they must either intersect or they are parallel.
If they are straight lines, then they define a plane in which both lines lie.
Parallel
Coplanar.

Yes - if they are straight lines.
