intersect
If they are in the same plane, then they share a common plane. Did you mean to say common point. If that's the case where they are in the same plane, but do not share a common point, then they are parallel lines.
Two or more lines meeting at a common point are called intersecting lines.
The common point is called the intersection.
Two lines that have a point in common are said to be intersecting lines. When they intersect, they share a specific coordinate point where they cross each other. For example, the lines described by the equations y = 2x + 1 and y = -x + 3 intersect at the point (2, 5). This common point is where both lines meet on a graph.
parallel

Two or more lines meeting at a common point are called intersecting lines.
If two lines cross they share a point of intersection. For two straight lines this is limited to one common point, for two circles two points and for complex lines like two sine waves the number of common points has no limit.

parallel
point I believe the word you're looking for is "intersection". Two non-parallel lines that lie in the same plane will have one point in common where they cross, and that point is the intersection.
Two lines with one point in common are said to intersect at that point. Any two straight lines with infinite length will eventually intersect each other, unless they are parallel to each other.
True
They would be intersecting.
coplanar
It is their intersection.
