Well, you are supposed to call an irregular quadrilateral an IRREGULAR QUADRILATERAL. Haha. There really isn't any name for a regular quadrilateral. You just call it a quadrilateral or whatever the shape is. You could call it a REGULAR QUADRILATERAL.

Oh, dude, that's an easy one. So, like, a quadrilateral with exactly 1 pair of parallel sides is called a trapezoid. It's like a fancy word for a shape that's a bit lopsided, you know? So, yeah, next time you see a wonky four-sided figure, just be like, "Hey, that's a trapezoid!"
Quadrilaterals usually have special names only if they DO have parallel sides, or some other special property. You might just call it "quadrilateral", or "a quadrilateral with no parallel sides".
