Usually none but it's quite possible for it to have two.
There are 3 different types: ordinary, isosceles and right which has 2 right angles
No.

A trapezium, also known as a trapezoid in American English, is a four-sided polygon (quadrilateral) with at least one pair of parallel sides. The parallel sides are referred to as the bases, while the non-parallel sides are called the legs. Trapeziums can be classified into different types, such as isosceles trapeziums, where the legs are of equal length, and right trapeziums, which have one right angle. Their properties and calculations, such as area and perimeter, differ based on the lengths of the sides and the angles involved.
4 right angles, no other angles.

No.
Many shapes have a right angles. For example, a right angled triangle, square or rectangle all contain at least one right angle. Trapeziums may also contain right angles. Any irregular polygon may also contain a right angle.

Letter L unless you count the ends as additional sides An irregular quadrilateral, such as certain trapezium. should that be trapezia or trapeziums?
It has 6 angles, none of which are right angles.
0 right angles
No, only squares and rectangles have four sides and four right angles (90 degrees). Parallelograms, trapeziums, kites, and rhombuses all have four sides, but they have different size angles.
A regular hexagon as no right angles. An irregular hexagon could have from none to as many as five right angles.
