A trapezoid.
A rhombus.
An irregular quadrilateral can have zero, one, or two pairs of parallel lines, but typically it has no parallel lines. By definition, an irregular quadrilateral does not have equal sides or angles, which means it does not conform to the properties of specific types of quadrilaterals like rectangles or parallelograms that have parallel sides. Thus, the most common scenario for an irregular quadrilateral is having no parallel lines at all.
A quardrilateral with 1 pair of parallel lines and have no equal sides is a trapezium.
Such a shape cannot exist.

A trapezoid is a quadrilateral with a set of parallel lines. Because it is a quadrilateral, it has four angles.
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.
A quadrilateral as described is a parallelogram. If the angles between the two sets of parallel lines are 90 degrees, the shape is a rectangle, a special form of parallelogram.
A quardrilateral with 1 pair of parallel lines and have no equal sides is a trapezium.
Such a shape cannot exist.

If the two lines being crossed are parallel lines then the corresponding angles are equal.
