An acute angle is less than 90 degrees. Therefore, as a rectangle has 4 right-angles (90 degrees) there are no acute angles.
A parallelogram has 0 or 2 acute angles. If the parallelogram happens to have four right-angled corners, it is still a parallelogram (and a rectangle), but no acute angles.
None because a rectangle has 4 interior right angles
