Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
What is a nonagram? A nine pointed star, perhaps. In any case, a general nonagram, like a general (ie non regular) polygram(!) has NO lines of symmetry.
Has nine sides
A nonagonal prism is a geometric polyhedron whose top and bottom are nonagons (polygons with nine sides) connected to each other by nine rectangles.
no, only single digit numbers are 8,3,1, and 0

In general, none, but there can be nine.
A regular Nonagon has nine lines of symmetry.

Nine. From each vertex to the middle of the opposite side.
There are 20.5 + 6 + 9 = 20 (Neither circles nor unclosed linear shapes are polygons.)
Any regular polygon of n sides, has an order of symmetry of n. Therefore, since a nonagon has nine sides, a nonagon has an order of symmetry of 9.
nonagon(also called an enneagon)

A nine sided 2-D shape (a nonagon) need not have any symmetry. It can have 1, 3 or 9 axes of symmetry: in each case from a vertex to the middle of the opposite side.
Yes. You can draw infinitely many straight lines from each point.
