Here are some other ways to say it, depending on the context:
* "tous" (meaning "all" in masculine plural) can be used on its own if the context is clear. For example, "Nous sommes tous d'accord" (We all agree).
* "nous toutes" (meaning "all" in feminine plural) is used when referring to a group of only women.
* "nous autres" is a less common way to say "all of us" and is used to emphasize the inclusion of the speaker in the group.
The choice of which expression to use depends on the context and the gender of the people involved.
