Since the question is unfinished, I'll assume the most obvious completion: "planes."
Yes, a triangular pyramid is composed of 4 non-co-planar points which form 4 intersecting planes.
A three-dimensional space contains at least four noncoplanar points. An example of this is the vertices of a tetrahedron, which consists of four points that do not lie in the same plane. This arrangement ensures that the points span three dimensions, demonstrating their noncoplanarity. Other examples include points in a cube or the corners of a pyramid.
No, intersecting lines form four pairs of supplementary angles
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
Four.
Four pairs, which intersect at the four vertices!
Yes, they do.

No, intersecting lines form four pairs of supplementary angles
They form four right angles.
yes
Perpendicular lines
Yes. They do. I disagree with the answer above, no they do not > that is 2 intersecting lines and there are only 2 angles there so the person above it incorrect
Intersecting lines
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
