There are infinitely many plane figures, not just five! A circle, ellipse, A triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, and on and on. And then there are mixed figures such as a semicircle, a segment of an ellipse. Not forgetting plane figures that have "random" boundaries.

All three of those figures is not a circle.
First of all, you did not provide measurements for the octagon. Second, surface area is meant for three-dimensional figures. Octagons are two-dimensional.
