a right angled triangle
Yes 1 pair
None
Its Impossible. For there to be a shape where all five lines meet perfectly and there to be two pairs of perpendicular sides, there must three right angles. Alternitavely, you could have 1 pair of perpendicular lines and two rights angles, but certainly not both.

No, but it does have 1 pair of opposite parallel lines of different lengths
a square
One pair of perpendicular lines would create one right angle. Some kites have one right angle.
a trapazoid
A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
