A rectangle, by definition is an irregular quadrilateral. It has two pairs of parallel sides.
it has 4 parallel lines

It depends on the irregular figure. A rectangle, for example, has two.
An irregular quadrilateral can have zero, one, or two pairs of parallel lines, but typically it has no parallel lines. By definition, an irregular quadrilateral does not have equal sides or angles, which means it does not conform to the properties of specific types of quadrilaterals like rectangles or parallelograms that have parallel sides. Thus, the most common scenario for an irregular quadrilateral is having no parallel lines at all.
A rectangle has 2 "SETS" of parallel lines. SO it has 4 parallel lines.Two pairs.

Two pairs
There are two sets of parallel lines in a rectangle, which is to say each of the two sides are parallel to each other.A rectangle has two set of parallel sides
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
It can have none, two, three or four.

Infinitely many. Every regular polygon with 2n sides has n pairs of parallel sides. Then there are irregular polygons which can have parallel sides. And there are also irregular shapes which have parallel sides.
