No unless it is in the form of a rectangle
By definition, a parallelogram two separate pairs has parallel sides. The only type of parallelogram that has perpendicular sides is a rectangle. All others have non-perpendicular sides.
No. A parallelogram has two parallel sides.
A trapezoid is a four-sided polygon (quadrilateral) that is not a parallelogram. In a trapezoid, at least one pair of opposite sides is parallel, while the other pair is not. This distinguishes it from parallelograms, where both pairs of opposite sides are parallel. An example of a trapezoid is a rectangle, which has one pair of opposite sides that are parallel and the other pair that is perpendicular to them.

No, a parallelogram does not have perpendicular sides by definition. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Perpendicular sides would form a right angle, which is a characteristic of rectangles, squares, and other types of quadrilaterals, but not parallelograms.
No. A parallelogram has two parallel sides.
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle or square. A parallelogram without perpendicular sides is a rhomboid or rhombus.
No. Not necessarily.
The question contradicts itself. A dodecagon need not have any perpendicular sides.

No.
A rectangle
Not normally but as a rectangle it has perpendicular sides that meet at right angles
