Note, that "all the shapes", as asked in the question would require an infinitely long answer. These is only a selection of shapes that have names. Many don't even have names.

An infinite number. A polygon with any number of sides can be equilateral (ie have sides of equal length).
The names of shapes based on the number of sides up to 10 are as follows: Triangle (3 sides) Quadrilateral (4 sides) Pentagon (5 sides) Hexagon (6 sides) Heptagon (7 sides) Octagon (8 sides) Nonagon (9 sides) Decagon (10 sides)
You specify shapes by the number of sides (or edges, different name) they have. The suffix -gon at the end of a word show how many sides it has in the words. For example, an octagon has eight sides; so if you see a shape with eight sides, it's an octogon. All shapes are known as polygons, which means it has three or more sides.
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.
