Assuming "rotational symmetry" means looks identical when rotated 180 degrees.

I think 7 although i'm not certainly sure, i'm sure that is between 7 or 9.
No numerical 7 has no lines of symmetry or 'mirror image'
It has 7 lines of symmetry

Order 7 if it is a regular heptagon; otherwise Order 1.
There are no right angles in an octagon.An 8 sided octagon normally has no right angles.
