Two lines may or may not lie in the same plane, depending on their relationship. If the lines are parallel or intersecting, they exist in the same plane. However, if the lines are skew, meaning they do not intersect and are not parallel, they lie in different planes. Thus, whether two lines lie in the same plane is contingent on their geometric arrangement.
parallel lines
Parallel lines would always lie in the same plane. They would need to be skew lines.
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.
No because only co-linear lines lie on the same plane

Skew lines cannot lie in the same plane.

Parallel lines would always lie in the same plane. They would need to be skew lines.
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
Intersecting lines are those that lie in the same plane and cross each other at some point. Unless they are parallel, lines in the same plane always cross.
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 lines lie in two planes, then the lines are coplanar.
