The answer will depend on the sizes and positioning of the squares. You could make a 16-sided polygon (8-pointed "star"), a 4-sided rectangle, or very many shapes between the two.
Side by side they would form a rectangle
A diamond is not a rigid shape unless it has a brace. A brace is a diagonal line you put inside shapes to make them rigid. Triangles are rigid so if you put a brace in a square to make two triangles the square is now rigid.
Rectangles are two dimensional objects- they have no thickness. Therefore you cannot "stack" them and so there will be no 3-D shape.
a parallelograma square and a rectangle
it is a plane shape because you said its a square
No, a diamond is not normally cut into a square shape.
a rectangle or square
a rectangle or square
The two triangles would make either a square or a rectangle.
A net is a two dimensional pattern that can be cut out and folded to make a 3-dimensional [solid] shape. A 2-dimensional shape, such as a square, does not have a net!
a rectangle because the corners can make the triangles and the other part is a square so that's how you know

No. A square is a two-dimensional shape, not an angle!
make a square with a triangle at the end and combine into one big shape
a square
a pentagon
