There are 4 (assuming a regular hexagonal prism), (a professional way is that seeing that it has 4 is dividing 8 by 2, for pairs).
There is 1 on the base and 3 more on its sides. 3 + 1 = 4.
A triangular based pyramid has zero pairs of parallel faces. In a triangular based pyramid, all three faces of the base are not parallel to the apex, which means there are no pairs of parallel faces in this type of shape.
It can have one, two or three pairs of parallel faces.
A triangular-based pyramid, also known as a tetrahedron, has no pairs of parallel faces. This is because all four faces (the triangular base and the three triangular sides) intersect with each other, and none of them are parallel to one another.
A cuboid. Or a hexagonal prism. In fact any prism whose base has an even number of sides will have three pairs of opposite parallel congruent faces. All but the cuboid will also have other faces but the question does not exclude them.
Yes. A square consists of two pairs of parallel lines!
Four.
A triangular based pyramid has zero pairs of parallel faces. In a triangular based pyramid, all three faces of the base are not parallel to the apex, which means there are no pairs of parallel faces in this type of shape.
For a uniform hexagonal prism, there are four pairs of parallel sides. On a hexagonal prism, the six side faces have interior angles of 120 degrees, so each face is parallel with one three over from it. The ends (base and top) are parallel and 90 degrees from each side.
It can have one, two or three pairs of parallel faces.
Only the base can have parallel edges since all other faces are triangular. So, at most one face.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Some of these have no parallel edges whereas a right hexagonal prism has 4 pairs of parallel faces.
A cube has three pairs of parallel faces and all faces are congruent.
A triangular-based pyramid, also known as a tetrahedron, has no pairs of parallel faces. This is because all four faces (the triangular base and the three triangular sides) intersect with each other, and none of them are parallel to one another.

A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
