Is it permissible to offer the Fidyah for making up missed days of Ramadan all at once, and what is the value of the expiation for four days?

It is permissible to give the fidyah all at once to several needy people at the same time. However, if the intention is to pay the fidyah for all days to a single needy person, some jurists have stipulated that this is not permissible, and that it is obligatory to give each expiation to a separate needy person, while others have permitted it. The more cautious approach, to avoid disagreement, is to give the fidyah for each day to a different needy person.
