There are infinitely many polygons and nobody can create a list or pictures of all of them.
There is no comprehensive list. In fact, there cannot be one. For example, polygons are named after the number of their sides and they can have infinitely many sides.

Not all polygons have an 'official' name. It is quite acceptable to call a polygon using the number of sides it has. For example a 101ogon. There is a list of some polygons names listed in the related question.
Triangle, rectangle, pentagon, hexagon, octagon. Though, there are much more names of polygons.
pentacontagon
pentacontagon
icosikaidi is the name for a 22 sided polygon. For a list of the names for polygons, see the related link.
There are infinitely many polygons and nobody can create a list or pictures of all of them.
A list of polygons would include the triangle, quadrilateral, pentagon, octagon, and the hexagon. Some additional polygons are the enneagon, the heptagon, the dodecagon, and the hexdecagon.

There are infinitely many of them so it is not possible to list their names. If the sides are all straight lines, they are collectively called polygons.
A polygon is a closed 2-dimensional shape whose boundaries are straight lines. These are its sides and a polygon can have 3 or more sides - with no maximum number. A 3 sided polygon is a triangle and a 4-sided one is called a quadrilateral. For 5 or more sides, the names are of the form n-gon where n is the Greek prefix for the number of sides. Since the number of sides is limitless, there are infinitely many polygons and so infinitely many names. It is obviously not possible to give a comprehensive list. See the link below for guidance on the prefices. However, you should use prefices for polygons with more than 12 sides only if you want to be unhelpful, obfuscatory or pretentious. If you wish to be communicative and helpful to your reader, it is much better (and wholly acceptable) to refer to a 17-sided polygon as a 17-gon rather than heptadecagon (and that's still a relatively easy name to decipher).
