| | People: hard to determine a rule with only three named polygons. |
 | | If you intend to skip one, the answer would be enneagon (however, the proper term for a 9 sided figure is nonagon). |
 | | There's no reason to choose dodecahedron (twelve), triskaidecagon (not a word, but I assume you used the Greek root triskaideka, thirteen), or icosahedron (twenty) given your beginning series. |
 | | If you intended to use etymologies all from one language or the other, then there's another problem: Square comes ultimately from the Latin (quadrum), where as Hex- and Hept- are from Greek roots. |
