Polygons are closed two dimensional shapes which are bounded by three or more straight lines. There are infinitely many of them so it is not possible to name them all.
All regular polygons. But there are also others which look like squashed versions of regular polygons. A "squashed" square makes a rhombus. Similarly there are squashed polygons with larger numbers of sides. They should be called equilateral polygons, but that phrase is not much used.

There are lots of different types of polygons Polygons are classified into various types based on the number of sides and measures of the angles.: Regular Polygons Irregular Polygons Concave Polygons Convex Polygons Trigons Quadrilateral Polygons Pentagon Polygons Hexagon Polygons Equilateral Polygons Equiangular Polygons
Regular polygons.
There are an infinite number of different polygons, and some have them have more than one name.
polygons perhaps
They are all polygons.

No. triangle can have 3 sides all the same length and angle or it can have sides of differing lengths and angles. same for all other polygons.
There would be too many to name. All regular polygons have a line of symmetry, but there are still polygons that don't.
They are named for the number of sides and angles their shape posses. For example, an octagon has both eight sides and angles.
