12 faces.
The number of parallel lines will depend on whether or not the prism is regular and right. In a regular right prism there are 10 parallel edges along the "length". 10 parallel lines make 45 pairs (1-2, 1-3, 1-4, ... 2-3, 2-4, ... etc).
Each line at a base has one parallel line at the same base and two at the opposite base. Each such quartet makes 6 pairs of parallel lines and there are 5 such quartets - so 30 pairs of parallel lines in the bases.
That makes a grand total of 75 pairs of parallel lines.
If the prism is based on regular decagons and it is a right prism, all 12 faces.
Yes. A square consists of two pairs of parallel lines!
A cube has three pairs of parallel faces and all faces are congruent.
3 pairs of parallel lines (2 dimensional) : regular hexagon.3 pairs of parallel faces (3 dimensional) : cube or rectangular prism (also known as cuboid)

A diamond has two pairs of parallel lines.
Here are three shapes that have two pairs of parallel lines: square parallelogram rectangle There are many polygons with at least two pairs of parallel lines. hexagon (has 3 pairs of parallel lines) octagon (has 4 pairs) decagon (has 5 pairs)
