Not quite right. Joe = Singular Joes = Plural Joe's = Singular possesive, i.e. Joe's car, but can also be used for contraction i.e. Joe's happy = Joe is happy. Joes' = Plural possesive, i.e. when you have more that one Joe that own stuff, i.e. Joes' wives, the wives of more than one joe. It's is the contaction of it is i.e. it's raining, in the case of the possesive for it [so it is a pronoun] the apostrophy is lost so it's just its, its car.
