Its shaft would have to be wide enough so as not to be represented by a single line. All lines would have to be straight.
Yes, there is. For example, a box-letter arrow is a polygon. A stick-letter arrow is not, because it is not in 1 piece
It is an irregular polygon.
If it is the outline of an arrow, and is made up of only straight lines, then it is a polygon. I tried to "draw" one, as an example, but the browser used at this site completely messed it up.
No but it is a quadrilateral because it has 4 sides
an arrow is or isn't a polygon?
An arrow can be a polygon. A polygon is any two dimensional plane figure. An arrow can, obviously, be a three dimensional object.
A polygon is a shape that is closed with straight sides and the sides do not overlap like these. I don't know if an arrow is a polygon.

An arrow head has 4 sides and it is a quadrilateral polygon

This question is very difficult to answer because of the ambiguity of what an "arrow" is. An arrow that you might fire from a bow is a three dimensional object and so is not a polygon. An arrow drawn as a straight line with a direction indicator at its head with or without tail feathers (for example <|----<< : oh, the graphics on this browser are so good, aren't they!) is not a polygon because the shaft is a line: a 1-dimensional object. An arrow such as the default one used to represent the cursor in Windows is a concave heptagon.
By definition, a regular polygon has all interior angles the same, but a concave polygon has some interior angles that are not identical. Also, it violates the axiom that all vertices lie on a circle.While it is possible to construct a polygon with equilateral sides, to be concave would require a form that is equally convex and laterally opposite. (An example is a 'solid arrow shape.')
