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.
