Dodecagon is the name for the regular 12 sided polygon, meaning that all its side lengths and angles are the same. Not sure if there is a name for a general 12 sided 2d shape.
As a 2D polygon shape it is an 8 sided octagon.
In geometry, a hendecagon is an 11-sided polygon.
A 14 sided polygon is called a tetrakaidecagon.
If we are talking about 2D polygon, Enneacontakaihexagon.
An 8 sided polygon is an octagon
