Think you just answered your own question. A plane is a line. Two planes= two lines.
skew lines
Two lines that lie on different planes but are not parallel.
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.
If lines lie in two planes, then the lines are coplanar.
If they are straight lines, then they define a plane in which both lines lie.

true * * * * * No, false. Any two straight lines that intersect define a plane in which both those lines lie.
Not necessarily. Points may lie in different planes.

Skew lines.
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.
If lines lie in two planes, then the lines are coplanar.
Parallel lines would always lie in the same plane. They would need to be skew lines.
One if the two lines meet, none otherwise. But skew lines do not lie in the same plane, by definition.
