Prove that the four points 1 3 1 and 1 1 -1 and -1 1 1 and 1 2 1 are lying on the same plane?

False. Over constrained, and not defining a single flat plane of the form:
Ax+By+Cz+D=0
Wolfram-Alpha inputs for the first 3 and last 3 sets of coordinates:
plane through (1,3,1) and (1,1,-1) and (-1,1,1)
plane through (1,1,-1) and (-1,1,1) and (1,2,1)
define different equations => different planes => therefore all 4 points do NOT lie on a common plane.

Is it true that the four coplanar points determine three unique plane?
No. If the four points are coplanar, they determine only one plane!
Can there be four points in one plane?
There can be any number of points on a plane, or even on a line - and any number of lines on a plane.
When are four points in a plane?
Any 4 points can lie in a plane, 3 points determine a plane and just take the 4th to be say the origin.
