That would be a rectangle. A square happens to be a particular type of rectangle, which also fits the bill.
trapezium, or trapezoid
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
A trapezoid can be constructed to fit the given description.
Any Trapezum is a Quadrilateral ., because it has four sides; the opposite two sides are parallel, However, it is NOT a rectangle, because all the four angles are NOT necessarily right angles(90 degrees).
A quadrilateral with only one set of perpendicular sides is typically a right trapezoid or right kite. In a right trapezoid, one pair of opposite sides is parallel, and the non-parallel sides meet at right angles. In a right kite, two pairs of adjacent sides are equal, and one pair of opposite angles is equal, with one set of sides meeting at right angles.

A trapezoid
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
A trapezoid is a quadrilateral with a set of parallel lines. Because it is a quadrilateral, it has four angles.
A trapezoid can be constructed to fit the given description.
Rectangles have 2 pairs of right angles.
I don't think this is possible. there is not a quadrilateral with these qualities. If it is a quadrilateral, it will automatically have parallel lines, but there is not one that has both. The closest one would be the trapezoid, with a set of parallel lines, but no right angle. The square and rectangle have two sets of parallel lines and 4 right angles.
Any Trapezum is a Quadrilateral ., because it has four sides; the opposite two sides are parallel, However, it is NOT a rectangle, because all the four angles are NOT necessarily right angles(90 degrees).
If it has at least one set of parallel sides, then at least one set of angles are congruent
It is a trapezoid that can have two right angles plus one obtuse angle plus one acute angle and the four angles add up to 360 degrees.
