No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.
A rectangle has 4 sides not the same length and 4 right angles.
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
It is a rhombus or a parallelogram.

A rectangle has 4 sides not the same length and 4 right angles.
Not possible ! If the shape has four right-angles, at least two sides must be the same length.
Rhombus
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
It is a rhombus or a parallelogram.
Rectangle
A rectangle.
A rectangle
There is no four-sided shape (quadrilateral) with four equal sides where no angles are the same. The diagonally-opposing angles must be the same, and opposing sides must be parallel. The only quadrilateral that fits that description is a parallelogram.
A square has all 4 sides the same length and its angles measure the same as well. A rhombus has all 4 sides the same length as well and the angles measure the same as well too.
A rectangle. The opposite sides at least must be equal if all four angles are 90o.
