a point
It is their intersection.
yes, two lines can be coplanar.

The greatest number of intersection points that four coplanar lines can have occurs when no two lines are parallel and no three lines intersect at the same point. In this case, the maximum number of intersection points can be calculated using the formula ( \frac{n(n-1)}{2} ), where ( n ) is the number of lines. For four lines, this results in ( \frac{4(4-1)}{2} = 6 ) intersection points.
In Euclidian geometry it's a point. In non-Euclidean geometry all bets are off.
It is their intersection.
A point or, if the lines are also collinear, the line(s).
yes, two lines can be coplanar.

If all three lines are parallel, there are zero points of intersection. If all three lines go through a point, there is one point of intersection. If two lines are parallel and the third one crosses them, there are two. If the three lines make a triangle, there are three points.
are two lines that are not parallel, coplanar, and do not intersect

No. If two lines intersect, then they're definitely coplanar.
No, not always. Skew lines are never coplanar, but parallel lines are.
Two coplanar lines that never intersect are called called parallel lines.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
Parallel lines.
