Firebase recommend creating a separate project for each separate "logo".

So if you have multiple variants of the same app (i.e. pro vs lite, multiple languages, admin vs regular), you should put those in the same project (unless you have a stringent reason to not do that).

If your multiple apps are of a different type, you should put them in separate projects (unless you have a stringent reason to not do that).
