A square has 4 right angles, and 2 pairs of equal, perpendicular sides.
Rectangle.
a parallelogram
The quadrilateral you are describing is a rectangle. A rectangle has four right angles, but its opposite sides are equal in length, leading to two pairs of equal sides. If you meant to describe a shape with four right angles and two pairs of unequal lengths, that would not be possible, as having four right angles inherently defines the shape as a rectangle or square.
The shape you are describing is a rhombus. A rhombus has two pairs of equal sides and opposite angles that are equal, but it does not necessarily contain right angles. Additionally, the diagonals of a rhombus bisect each other but do not intersect at right angles unless it is a square.

a parallelogram
A shape that has 2 pairs of equal sides and no right angles is a kite or a parallelogram. In a parallelogram, each side is equal to the one directly opposite; in a kite, the equal sides are adjacent to one another.
