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 trapezium or trapezoid.
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.
trapzoid
Only if it is a trapezoid (US usage) with one set of parallel sides, or a parallelogram with both sets of opposite sides parallel. The term quadrilateral only means that the shape has 4 sides.
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 kite or a parallelogram, depending on whether the equal sides are adjacent to, or opposite one another.

trapzoid
A trapezoid is unique because it is a quadrilateral that has one set of parallel sides, and one set that is not parallel.

Yes. A trapezoid has four sides, and hence, is a quadrilateral.* The US definition of a trapezoid has one set of parallel sides. In the UK, this is called a trapezium.
A quadrilateral must have one and only one set of a parallel sides to be a trapezoid.
A trapezium (US) has no sides parallel, while a trapezoid has one set of unequal parallel sides.
