the lines which are not parallel to each other are non collinear lines
None. In ordinary geometry, a line contains an infinite number of points and, by definition, they are all collinear. In projective geometry, however, you can have three lines in the form of a triangle. Each line has only two points on it, so it cannot have 3 points collinear.
No. Collinear means on the same line. So collinear points all must lie on the same line. Not parallel lines.
Collinear lines lie on the same straight line passing through the same points and they are coplanular lines when meeting on the same plane.
Yes.
The definition of a non-collinear line is that this is a line on which points do not lie on one line. The opposite of this is a collinear point. Collinear points refer to three points that do fall on a straight line.

Yes,actually that the definition of collinear.
Not sure about complanar. Coplanar lines can be collinear but need not be.
Definition for collinear and non collinearPoints that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are non collinear points.
Collinear lines lie on the same straight line passing through the same points and they are coplanular lines when meeting on the same plane.
Yes.
parallellines
only 1 lines can contain 3 collinear points. Maybe you mean coplanar?
2 points determine a straight line and are always, by definition, collinear.
