it depends on what you mean by a diagonal. If you take a diagonal to mean a line from one corner to the "opposite" corner, then a nonagon doesn't have any, and a decagon has five. The reason a nonagon doesn't have any, is that the corners aren't opposite each other.
hexagon, heptagon, octagon, nonagon, decagon, undecagon, dodecagon .... etc

They are all polygons which means that they are plane areas enclosed by straight sides. A heptagon has 7 sides, a nonagon has 9 and a decagon has 10.
A nonagon is a polygon with n vertices (or 9 sides).
