Parallelogram
It is an irregular pentagon.
A square if it has 4 equal angles too, or a rhombus if it has two obtuse and two acute angles.
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
The shape you are describing is a trapezoid. A trapezoid has two pairs of parallel sides, with one pair longer than the other. It can have two acute angles and two obtuse angles, depending on the lengths of the sides. The acute angles are typically smaller than 90 degrees, while the obtuse angles are larger than 90 degrees.
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.

a trapezium
A diamond shape, often referred to as a rhombus, is not classified as obtuse, acute, or equilateral because these terms describe specific types of angles or triangles. A rhombus has equal-length sides and opposite angles that are equal, but the angles can be either acute or obtuse. Thus, a diamond shape can have both acute and obtuse angles, depending on its specific dimensions.
