How about a rectangle which is a quadrilateral with sides of different lengths
a rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
The quadrilateral you are describing is a scalene trapezoid. It has two sides of unequal lengths (the long sides) and two other sides of equal, shorter lengths (the short sides). This shape does not exhibit reflective symmetry and lacks right angles, fitting your criteria perfectly.
The quadrilateral you are describing is a rectangle. A rectangle has four right angles, but its opposite sides are equal in length, leading to two pairs of equal sides. If you meant to describe a shape with four right angles and two pairs of unequal lengths, that would not be possible, as having four right angles inherently defines the shape as a rectangle or square.
They are unequal in length but one of the bisects the other at right angles.
A trapezoid can have 2 right angles and 1 pair of opposite parallel sides of different lengths. The 4 interior angles will add up to 360 degrees.

That's a triangle in which all three sides have three different lengths.
A trapezium (has only one pair of unequal parallel lines).

A shape with four unequal sides is called an irregular quadrilateral.
A right trapezium or an irregular quadrilateral.
