Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
There is no specific term but you could try "non-coplanar".
Perpendicular lines that that intersect at 90 degrees are right angles.
Perpendicular lines are two lines that intersect to form four right angles.
Skew lines are a term for lines in geometry. They mean two lines that are not parallel, but do not intersect either. It is only possible in three dimensions and up.

coplanar
The lines are perpendicular.

Perpendicular lines are two lines that intersect to form four right angles.
If they intersect they are refered to as skew lines and if the do not the term for this is that they are parallel lines.

Two lines that intersect and form 90-degree angles (right angles) are "perpendicular" to each other. You would call them "perpendicular lines."
Coplanar vectors lie within the same plane, meaning they can be represented by arrows with their tails at the same point. Collinear vectors, on the other hand, lie along the same line, meaning they have the same or opposite directions. In essence, coplanar vectors can be parallel or intersecting within the same plane, while collinear vectors are always parallel or antiparallel along the same line.
On angles arms is the term used to describe lines.
Point is not an undefined term. It can be defined as a mathematically precise location, or as the place where two lines intersect.
