Intersecting lines are two lines that cross in a coordinate plane. So, yes, intersecting lines cross.
yes perpendicular lines are at right angles to each other. Therefore they have to touch eventually
No
Whether perpendicular lines meet at right angles depends on what they are perpendicular to. Perpendicular is a relational word; this is perpendicular to that.When a pair of lines are perpendicular to each other, they are properly called "mutually perpendicular". Many people (including mathematicians) say just "two perpendicular lines" when they really mean mutually perpendicular, if it is clear from the context that that is what is meant.However, there exists at least one teacher, at least one of whom is a mathematician, who will on at least one occasion attempt to catch out at least one of his students by leading that student to make an assumption the validity of which has not been rigorously proved.This often happens when a teacher is trying to show his pupils the art of rigor in mathematical proof. (The previous paragraph is to give you some idea of what a rigorous proof looks like.)Just to formally answer the question, mutually perpendicular lines on a plane always meet at right-angles - that's what perpendicular means.
Of course. Any lines in the same plane (if extended far enough) that are not parallel must intersect.
Yes, two perpendicular coplanar lines will touch. If you have two lines that, by definition, form a 90 degree angle (i.e., they are perpendicular) and are both on the same plane, eventually they must cross at some point on that plane. They will have exactly one point in common. If, however, the lines were, by definition, "perpendicular skew" lines, they would never cross because the definition forbids it.

No
Yes.
Yes at 90 degrees.
Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.
Perpendicular lines intersect each other at 90 degrees but parallel lines never touch each other
No, parallel actually means that the lines will never touch or cross

no because Perpendicular is a 90 degree angle and 90 degrees have no slant or anything they will always be parallel
By definition, perpendicular lines are those which meet in a right angle. So, yes, they have to meet in order to be "perpendicular". Parallel lines may, or may not, meet, depending on how you choose your axioms. In Euclidean geometry, parallel lines never meet. In certain types of non-Euclidean geometry, they can meet.
