A triangular prism has 9 parallel lines
Three.
Each of the nine edges have another edge running parallel to them.
There are 9 edges. It has three edges which are parallel to each other (along the length of the prism) AND it has three pairs of parallel edges - at the top and bottom of the prism.
One pair because opposite cross-section faces are parallel to each other.

A triangular prism has 5 faces, including one parallel pair; any of the faces might be considered a "base" depending on its orientation.
One pair because opposite cross-section faces are parallel to each other.
A triangular prism has nine edges, three edges that are parallel to each other on the top and bottom of the prism, and three surrounding edges. It also has five faces and six vertices.
Nine edges (three of them are parallel) and six vertices (corners).
