Yes, it can.
any given line can have an infinite number of possible points.
Yes, if no endpoints are defined.
Given a line, there are an infinite number of different planes that it lies in.
There are an infinite number of points on a line.
infinite number of lines

It does not. It is infinite
An infinite number. Each point on a line, however small the line is, can have a perpendicular through it. And since there are an infinite number of points on any line, the answer is an infinite number.
An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
-- An infinite number of different planes can intersect the same line. -- The same line can lie in an infinite number of different planes. -- An infinite number of different lines can intersect the same plane.
It is infinite
