Square
There is no polygonal shape which has exactly those angles. It is possible for a concave polygon with 6 or more vertices to have the given angles.
Both a 'kite' shape and a right-angled trapezium can have exactly two right angles
A pentagon
A kite and a trapezium can have exactly two right angles.
A square and a rectangle both have exactly 4 interior right angles of 90 degrees that add up to 360 degrees.

A star is not a specific shape: it is a generic word for a shape which has an even number of vertices. The interior angles at alternate vertices are usually reflex angles. A star can have six or more vertices.
A trapazoid
It is a pentagon - like a child's drawing of a house and its roof.
Both a 'kite' shape and a right-angled trapezium can have exactly two right angles
A Hexagon.
A pentagon
A frustum of a cone, or a sphere sliced by two planes are a couple of examples.
A regular octagon has no right angles. An irregular octagon could have o,1,2, or three right angles, depending on its shape.
A kite and a trapezium can have exactly two right angles.
Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing.
