#1. ok
#2. Any three distinct collinear points are coplanar
How can this not be true? Every line lies in some plane, so any set of collinear points must lie in a plane.
3 points determine a plane, unless they are collinear, but they still must lie in the same plane(s). Many planes contain a line, and so must also cintain the three points in that line.
#3. false - skew lines do not intersect, and they are not parallel
they are not coplanar.
#4. ok - I'm surprised that you got this, but not #3.
Coplanar lines are either parallel or intersecting.

oh, yeah shoot. Thanks
For num 2, I read it as "Any three distinct coplanar points are collinear"
My bad
For num 3 though, I answered "sometimes true", neither false nor true
Anyway, thank you
