It's quite acceptable to call it a 24-agon but what's more important is knowing how to work out its properties
A 24-gon is possible
Just call it a "24-sided polygon".
An icasagon is a polygon with 24 sides. The name comes from the prefix "ica-" which indicates 20, and "-sagon," which denotes a shape or polygon. Therefore, an icasagon has a total of 24 edges and vertices.
Divide the number of vertices by 3. Find the name of the polygon with that many sides. The prism has that polygon as a base. For example, a prism with 24 vertices. Divide by 3 so that is 8. An 8 sided polygon is an octagon. The name is an octagon-based prism.
The proper name is icositetragon. Most people, including mathematicians, will use 24-gon since that effectively communicates the size of the polygon. But, if you want to appear pretentious or be obfuscatory, by all means use the Greek prefices.
The constructed polygon name for a 24-sided regular polygon is an icosikaitetragon.

a 24 sided polygon is a icosikaitera.

interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°

It cannot be a regular polygon with interior angles of 24 degrees since the smallest interior angle in a regular polygon is 60 degrees. If it is an irregular polygon, then any one of them, with 3 or more sides, can have an angle of 24 degrees.
