No, two straight lines can intersect at only one point and that is their point of intersection.
Point.
A point can be intersected by infinitely many lines. Two points intersect in only one line. Three points either intersect in a line or not at all. This is only considering two dimensions.
Such a point is called the orthocenter. Even the fact that all three altitudes intersect at a point is quite interesting because only two lines are guaranteed to intersect at a point, but we have three.
No, that is not true.
No, only three lines can intersect at a single point.
Any number of lines can intersect all at the same point. Think of a circle. Now think of all of its diameters.
Assuming that the none of the lines are parallel, they can intersect (pairwise) at three points. Otherwise, the question is tautological.

This is true. If three straight lines are drawn, they can only intersect at two points. That is, each line will only intersect with another once.
Perpendicular lines intersect at one point only.
Such a point is called the orthocenter. Even the fact that all three altitudes intersect at a point is quite interesting because only two lines are guaranteed to intersect at a point, but we have three.
No, that is not true.
Yes.
In Euclidean plane geometry two infinitely long straight lines intersect at only one point
