It depends. Most parallelograms don't have all right angles. However, there is a special type of parallelogram that has all right angles. You probably know this shape by its proper name, a rectangle.
rectangle
Rhombus

They are supplementary.
Four.
Yes it does - it has two pairs of equal angles.
Yes, and adjacent angles are supplementary (add to 180°)
a parallelogram has 4 angles it is pretty much a rectangle that is tilted
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
Yes. All 90-degree angles are "right angles", and all right angles are 90 degrees. Anything else is not a right angle.
A rhombus.
All of the interior angles in it are.
