Equilateral parallelograms.
No, not all diagonals are perpendicular in all parallelograms. In general parallelograms, the diagonals bisect each other but are not necessarily perpendicular. However, in specific types of parallelograms, such as rhombuses, the diagonals are indeed perpendicular. Thus, the property of perpendicular diagonals is not a characteristic of all parallelograms.
No.
That is true for some parallelograms but not all. For example, the diagonals of a rhombus, kite or square are perpendicular, but those of a rectangle or general parallelogram are not.
No. No. No. No.
A rhombus has 4 equal sides and the diagonals are always perpendicular

Parallelogram and a rectangle
No. No. No. No.
The diagonals of a rectangle are never perpendicular but the diagonals of a square are perpendicular
The diagonals of a square are always perpendicular.
Yes, the diagonals of a rhombus are perpendicular.
Some of them (rectangles) do.
A rhombus has 4 equal sides and the diagonals are always perpendicular
No. The diagonals of a rhombus are perpendicular only if the rhombus is a square.
No but the diagonals of a square, rhombus and a kite are perpendicular to each other
