parallel lines
Lines that intersect at right angles.
Perpendicular lines that that intersect at 90 degrees are right angles.

Parallel lines in the Euclidean plane do not intersect but all parallel lines in the projective plane intersect at the point at infinity.
Lines which are parallel. All other lines on the same plane eventually intersect.
Perpendicular lines are straight lines that intersect each other at right angles which is 90 degrees
All non-parallel lines in a plane will intersect at some point in the plane.
It depends on how you define "ways" and how you define "lines" and how you define "intersect" and what kind of geometry you're talking about, but in Euclidean geometry, lines either never intersect, or they intersect at a single point, or they can intersect at all points within the lines.
Parallel lines will never intersect. They will stay an equal distance apart at all points.
Skew lines can simply be described as two lines that are not coplanar (they are not in the same plane). This means that they do not intersect and are not parallel.

Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
