The word for shape in Spanish is figura or forma and if you want to explain what shape something is, you simply have to say "Tiene la forma de un _____".
Most of the shapes here are masculine nouns and would be preceded by the masculine indefinite article un; the only exception in the following list is star/estrella, which is feminine and has the indefinite article una.
