A decagonal prism has 12 faces
If the prism is based on regular decagons and it is a right prism, all 12 faces.
A triangular prism has 9 parallel lines

It depends on a decagonal what. A decagonal prism has 20 vertices. A decagonal pyramid has 11 vertices.
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.
5 pairs of parallel lines, plus a set of 5 parallels.
It depends on a decagonal what. There will be different answers for a decagonal pyramid, prism, dipyramid, etc.
