As far as I know, there is no "regular" 4 pointed star.
However, if you have a 4 pointed star, you can draw a circle through it's inner points and a second circle around its outer points. If we say that the inner circle has radius "r" and the outer circle has radius "R", that the angle, "a", of the star's points are:
a = atan(2r / (R√2 - r)
If the outer circle is twice as big as the inner circle, this becomes:
a = atan(2r / (2r√2 - r) = atan(2 / (2√2-1) = 47.5°
A four pointed star.
That depends on the size of the star.
A rectangle has four right angles, while a regular pentagon has none. Therefore, a rectangle has more right angles than a regular pentagon.

A polygon with 4 right angles is a rectangle. (A square is a "regular" rectangle.)

if you mean 4 pointed star like a ninja star, there's a pretty good video showing you how here: http://foldsomething.com/origami-videos/4-point-star-ninja-throwing-star-shuriken/
A polygon is a plane figure whose boundary is formed by straight lines. The simplest example is a triangle. A square, rectangle, kite, etc are common 4 sided polygons. Polygons can have angles that are greater than 180 degrees (reflex angles), so a 5 pointed star is a ten sided polygon. There is no limit to the number of sides a polygon can have. If all the sides and angles of a polygon have the same measures, it is called a regular polygon.

The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
Draw a regular five-pointed star. Place a coin at each of the points and each of the intersections.
A regular square is just a square with 4 equal and parallel sides, and 4 equal right angles.
