A concave octagon has is an 8-sdided figure in which one or more vertices (interior angles) are more than 180° , producing a shape with an inward bow, or a concavity (think of a cave).
The name of an 8-sided polygon is octagon
It is a concave octagon.
It could be a triangle, a quadrilateral, a pentagon, a hexagon or even an octagon if they are two concave quadrilaterals.

The name of an 8-sided polygon is octagon
It is a concave octagon.
A bigger square, a rectangle, an irregular concave hexagon, an irregular concave octagon are all possibilities.
It could be a triangle, a quadrilateral, a pentagon, a hexagon or even an octagon if they are two concave quadrilaterals.
Dragon is the answer
None, because there is no such shape. There is a heptagon (7 sides) or an octagon (8 sides), and the answers will be different depending on what you meant. In their convex form, either can have at most 3 right angles. But a concave heptagon can have any number up to 6 right angles. A concave octagon can have up to 7 interior right angles. It can, in fact have all eight if reflex right angles (270 deg) are allowed.

The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
