No. A parallelogram is a special kind of quadrilateral.
A shape that is a parallelogram but not a quadrilateral doesn't exist.
It's not a matter of 'finding' it. Either the quadrilateral is a parallelogram,or else it is not one.If the opposite sides of the quadrilateral are parallel, then it's a parallelogram.
The second statement is false.
"It has four sides" is a description that does not guarantee that a quadrilateral is a square.
False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.
None of the conditions on the list that accompanies the question guarantees that a quadrilateral is a parallelogram. But then, none of them prevents it either.

Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
Either a square or a parallelogram fit this description.
A parallelogram must have 4 sides and so it must be a quadrilateral. However, the sides of a quadrilateral need not be parallel so a quadrilateral need not be a parallelogram.
A quadrilateral is not necessarily a rectangle. The only time this is not true is in the case of a square on a quadrilateral without four 90 degree angles.
A parallelogram. A square or rectangle would also technically fit this description.
A kite would fit the given description
