An irregular quadrilateral.
rhombus
square and rectangles are technicality squares
a pentagon
Not all shapes with four right angles have exactly two lines of symmetry. For example, a rectangle has two lines of symmetry (one vertical and one horizontal), while a square, which also has four right angles, has four lines of symmetry. In contrast, a non-square rectangle may only have the two symmetry lines, but other configurations could exist that alter this symmetry. Thus, the number of symmetry lines depends on the specific shape.
A shape that has 2 right angles, only 1 set of parallel sides, and no lines of symmetry is a right trapezoid (or right-angled trapezium). In this trapezoid, the two non-parallel sides are not equal in length, contributing to the lack of symmetry. The right angles are formed between one of the parallel sides and one of the non-parallel sides.
octagon
rhombus
A rectangle. Obviously the right angles are in the four corners of the rectangle. The lines of symmetry occur across the horizontal and vertical. There are no lines of symmetry on the diagonal.
