A concave is not a shape. It is a characteristic of one. It is like asking how many parallel lines a small has.

How many pairs of parallel lines does a parallelgram have?
it has too parallel lines!
How many pairs of parallel lines does a pentagon have?
A pentagon has no parallel lines.
How many parallel lines does a nonagon have?
On a quick estimate, I would think 18, 9 for each interior side and another 9 for each interior angle. * * * * * A nonagon has only 9 lines so the above answer is nonsense. With 9 lines you can have at most 4 pairs of parallel lines (and one not parallel to any). Or you could have a concave nonagon with 1 pair, 1 triplet and 1 quartet of parallel lines, or some other combination.
Are concave angles parallel?
Angles cannot be parallel.
