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).
not necassarily
yes, any three non collinear points will make a circle, however, four or more will not
-lie in the same plane -are collinear
-- The four corners of a square are non-collinear. -- The four corners of a rectangle are non-collinear. -- The four vertices of any rhombus, parallelogram, or quadrilateral are non-collinear. -- Any four vertices of any polygon with more than 3 sides are non-collinear. -- The three vertices of any triangle are non-collinear, and they stay that way when you add any other point on the same piece of paper. -- Any four points on any circle, ellipse, parabola, or hyperbola are non-collinear. -- If at least one point is on a different floor of the house from the other three, then the four points are non-collinear. -- Make three dots on a piece of paper. Cover them up. Walk away for a few minutes. Come back. Make another dot on the paper. Uncover the first three. We're almost positive that the four dots are non-collinear.

Just one.
I dont think that "If four points are collinear they are also coplaner," is the same thing as "If four points are coplaner they are also collinear,". The definition of collinear is at least three points on the same line. To define a plane is to have threenoncollinear points.
exactly nine planes! * * * * * I would have said 4 - corresponding to the four faces of a tetrahedron. Of course, non-collinear does not mean non-coplanar so all four points could be in the same single plane!
Yes. On any straight line you can find an infinite set of 4 points which are collinear.
Yes, they are.
Yes, they are.

all of them are collinear they lie in the same plane
