Yes. Three co-linear points define a line, and therefore also lie on a plane, but those three points do not necessarily define only one plane. You need three points, not co-linear, to uniquely define a plane.

because coplanar is coplanar and collinear is collinear!!
Yes, collinear points are also coplanar.
Any set of points that are collinear must be coplanar.
Yes, four collinear points are also coplanar. Collinear points lie on the same straight line, and any set of points that includes at least three points can be contained within a plane. Therefore, since collinear points can be defined within a single plane, four collinear points must be coplanar.
A set of 3 points will always be coplanar, but will only sometimes be collinear. Collinear points are always coplanar as well.
No but they are always coplanar.
no.
Yes.

Not sure about complanar. Coplanar lines can be collinear but need not be.

3 coplanar points may or may not be collinear. 3 collinear points must be coplanar.

True.
