Not always, a square is a quadrilateral shape
Ordinarily no, as that's simply a math term for a square but they can be for example-Rhombuses, rectangles, kites, parallelograms, and trapezoids are all irregular quadrilaterals.
Not all irregular quadrilaterals share the same properties; however, they all have four sides and angles that are not equal or do not have equal lengths. Irregular quadrilaterals can have varying side lengths and angles, distinguishing them from regular quadrilaterals like squares or rectangles. Examples include trapezoids and general quadrilaterals that do not conform to specific classifications.

hehe , your face
Always 360 degrees
There are always 2 diagonals in any quadrilateral whether or not it is irregular or regular

no
square, rectangle, trapezoid, rhombus, parallelogram, kite, and irregular quadrilaterals
quadrilaterals
Quadrilaterals- Squares, Rectangles, Rhomboids, Parallelograms, kites, chevrons, trapezoids, and irregular quadrilaterals.
Quadrilaterals are polygons. They can be regular or irregular.

A parallelogram, a rhombus, kites, arrowheads, trapezium and irregular quadrilaterals. However, some kites, arrowheads, trapezium and irregular quadrilaterals can have one (or more) right angles.

ALL quadrilaterals have 4 angles
A kite or some irregular quadrilaterals.
