points
Yes, if no endpoints are defined.
Given a line, there are an infinite number of different planes that it lies in.
Infinitely many. There an infinite number of points on a line and each point can be an end point of two rays.
-- 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.
points
A line, ray, or line segment contains an infinite number of points.
Yes, if no endpoints are defined.
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.
Given a line, there are an infinite number of different planes that it lies in.
Infinitely many. There an infinite number of points on a line and each point can be an end point of two rays.
An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
Yes, except when the line is in the plane. In the latter case, they intersect at each point on the line (an infinite number).
It does not. It is infinite

-- Each meridian ( 'line' ) of longitude represents all of the infinite number of points on the Earth's surface that have that one specific longitude. -- Each parallel ( 'line' ) of latitude represents all of the infinite number of points on the Earth's surface that have that one specific latitude.
-- 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.
