polygons perhaps
lots of them, depends on what kind, but one is polygons
There would be too many to name. All regular polygons have a line of symmetry, but there are still polygons that don't.

There is no special name: they are polygons, as are shapes with 3 or 3 million sides.
There is no specific name for such shapes.
