Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.
Yes- planes contain infinitely many points and every pair of points in plane determine a line in that plane, so every plane contains infinitely many lines.

That is a plane.Any one of infinitely many planes.

Anything that contains the line must contain every point on the line, so "a point on the line" doesn't give us any more information. You're just asking how many planes can contain the line. Now imagine setting a wood panel down on a tight-rope. How many different ways can it set there before it falls off ? A lot, right ? An infinite number of planes can all contain your line. (And all of its points.)
There is only one such plane.
Given a line, there are an infinite number of different planes that it lies in.
If 2 points determine a line, then a line contains infinitely many planes.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.
An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
one
an infinite number; no limit
