All polygons have 3 or more sides having exterior angles that add up to 360 degrees and the first 10 can be classed as follows in order of their geometrical names, number of sides, sum of interior angles and number of diagonals:-
1 Triangle: 3 sides, 180 degrees and no diagonals
2 Quadrilateral: 4 sides, 360 degrees and 2 diagonals
3 Pentagon: 5 sides, 540 degrees and 5 diagonals
4 Hexagon: 6 sides, 720 degrees and 9 diagonals
5 Heptagon or Septagon: 7 sides, 900 degrees and 14 diagonals
6 Octagon: 8 sides, 1080 degrees and 20 diagonals
7 Nonagon: 9 sides, 1260 degrees and 27 diagonals
8 Decagon: 10 sides, 1440 degrees and 35 diagonals
9 Undecagon: 11 sides, 1620 degrees and 44 diagonals
10 Dodecagon: 12 sides, 1800 degrees and 54 diagonals
Note that all polygons can be regular, irregular, congruent or similar
It not necessary to know their names but what's more important is knowing how to work out their properties
It's not necessary to know their exact names but what's more important is knowing how to work out their properties
yes they all have special names.

It not necessary to know their names but what's more important is knowing how to work out their properties
It is quite acceptable to call them an 11-agon to a 100-agon but what is more important is knowing how to work out their properties.
It's not necessary to know their exact names but what's more important is knowing how to work out their properties
It's quite acceptable to call them a 57-agon or a 99-agon but what's more important is knowing how to work out their properties.
It's quite acceptable to call it a 60-agon or a 70-agon but what's most important is knowing how to work out its properties.

Its not needed to know their exact names because a 61-agon to a 69-agon will suffice but what's more important is knowing their properties
yes they all have special names.
Squares and polygons. DumbA**
