A trapezium has only one pair of parallel sides
It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.
A trapezium has 1 pair of opposite parallel sides of different lengths
7 sides
A trapezium has 1 pair of opposite parallel sides of different lengths. Note that sometimes a trapezium is called a trapezoid
How many parallel sides has a trapezium?
A trapezium has only one pair of parallel sides
No. A parallelogram has two pairs of parallel sides. The trapezium has only one pair of parallel sides. (This applies the definition of a trapezium as a 4-sided figure with exactlytwo parallel sides.)
It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.

Trapezium.
2 parallel sides or 2 pairs of parallel sides?

All the sides of a trapezium are not equal. Only two sides, which are not parallel, of a trapezium can be equal and such type of trapezium is called isosceles trapezium.
It depends on where you are. If in the USA, a trapezium has no parallel sides. For everywhere else, a trapezium has one set of parellel sides (which is called a trapezoid in USA).
It may have none. A trapezium (US) has no parallel sides. A trapezoid (US, known elsewhere as a trapezium) has one side of parallel sides.
