It has two 5-tuples and 5 pairs of parallel lines. It need not have any line of symmetry.
A pentagonal prism has 5 vertical axes of symmetry that pass through the center of each of the pentagonal bases and the midpoint of the opposite base edges. Additionally, it has 1 horizontal axis of symmetry that runs through the midpoints of the two pentagonal bases. Therefore, a pentagonal prism has a total of 6 axes of symmetry.
It can have one, two or three pairs of parallel faces.

No because a pentagonal prism has a unified cross-section
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.

pentagonal based prism
5 pairs of parallel lines, plus a set of 5 parallels.
Yes, its bases will normally be parallel.

No because a pentagonal prism has a unified cross-section
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.
A pentagonal prism has 5 planes of symmetry. This is because it can be divided into 5 identical sections by planes passing through the center of the prism and perpendicular to its bases. Each of these planes divides the prism into two equal halves that are mirror images of each other.
Penta means 5. In other words none if it is a regular prism.
