There are 9 diagonals in every hexagon.
To see why, select any one of the 6 vertices. There are 5 other vertices to which it can be joined. But the lines joining it to the two adjacent vertices (one on each side) are not diagonals but sides of the hexagon. So, from each vertex, you get 3 diagonals.
The first vertex can be selected in 6 ways so it would seem that you have 6*3 = 18 diagonals. However, you will then be counting each diagonal twice: once from each end. So the correct answer is 18/2 = 9.
In general, a polygon with n sides has n*(n-3)/2 diagonals. Also, whether or not it is regular is totally irrelevant.

How many diagonals does a concave hexagon have?
A concave Hexagon is that hexagon which has one of its internal angle greater than 180 degrees. It can have 8 diagonals. As compared to regular hexagon (Also convex hexagon) it has one less number of diagonals. This is because one line joining two of its vertices (that are at the end of sides forming >180 angle) fall outside the hexagon.
