Not EVERY quadrilatiral. Some, for instances :Rectangles, Squares, Parallelograms and Rhombus' are, as they have 2 sets of parellel lines that are equal. (As in the opposite lines are equal with each other) however you could draw a four sided shape with irregular sides.

No. The only regular quadrilateral is a square. Being a regular polygon requires all sides as well as all angles to be equal. A rectangle fails the first requirement, a parallelogram and a rhombus fail the second - unless they are squares.

Which quadrilaterals are regular?
Only a square.
Which two quadrilaterals do not have all sides of equal length?
There are infinite amounts of quadrilaterals that have sides that aren't all equal. In regular quadrilaterals, however there are rectangles and kites that have uneven lengths of sides.
What is the fourmula to find area?
In regular quadrilaterals, it's length times width.
How many diagonals in irregular quadrilaterals?

How many regular quadrilaterals are there?
There is only one regular quadrilateral, the square. A regular polygon must have equal sides and equal angles, and in the case of quadrilaterals that is a square.
