Just one plane.
The answer depends on the number of point. One point - as the question states - cannot be non-collinear. Any two points are always collinear. But three or more points will define a plane. If four points are non-coplanar, they will define four planes (as in a tetrahedron).
Exactly one.
Exactly one.
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.
Just one plane.
You can have an infinite number of planes passing through three collinear points.
3 non-collinear points define one plane.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.

Only one if they are non-collinear. An infinite number if they are collinear.
