yes. For example the corners of a square, or on the circumference of a circle.
You have to have three or more points to have non-colinear points because any two points determine a line. Noncolinear are NOT on the same line.

what is noncollinear because it was a point
yes. For example the corners of a square, or on the circumference of a circle.

No. For example, consider the vertices of a tetrahedron (triangle-based pyramid).
noncollinear
Since collinear is points that lie on the same line, and you need two points to form a line so those 2 points are collinear. So the opposite of that is noncollinear.
Any Euclidean plane has infinitely many points.
