Answer 2

According to this page

http://mathworld.wolfram.com/Collinear.html

it says "Three or more points P1, P2, P3, ..., are said to be collinear if they lie on a single straight line L"

Answer 3

one set of 3 points that lie on a line are: L, D, C

another set is L, F, E

I don't see any other set of collinear points, so it looks like you have 2 sets of collinear points
