Infinitely many planes contain any two given points- it takes three (non-collinear) points to determine a plane.
Given a line, there are an infinite number of different planes that it lies in.
Exactly one.
Only one plane can contain three specific points.
If the points are collinear, that means there's only one straight line. An infinite number of different planes can be drawn that contain one straight line.
Infinitely many planes contain any two given points- it takes three (non-collinear) points to determine a plane.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.
Given a line, there are an infinite number of different planes that it lies in.
There are no planes containing any number of given points. Two points not the same define a line. Three points not in a line define a plane. For four or more points to lie in the same plane, three can be arbitrary but not on the same line, but the fourth (and so on) points must lie in that same plane.
One.
Exactly one.

Only one plane can contain three specific points.

There will always be a single plane through all three points.
