"rentrerons à la maison"

There are several ways to say ‘return or go back’ in French and they have specific usage and meaning. They are therefore not interchangeable - all very confusing initially for non-native speakers. Only ‘rentrer’ fits here - as they are going back to the place they are staying at.

Retourner is almost a faux ami in English as it means something different than what its similarity with the English "to return" implies. Think of it as "going back to a place for a brief time without staying there".
Je retourne chez mois pour récoupérer mon manteau. -- I'm going back home to pick up my coat.

Use rentrer if you're talking about coming back and staying someplace:´
Tu rentres quand? -- When will you be back?

Revenir is "coming back", i.e., returning after an absence.
Il revient bientôt. -- He'll be back shortly.
