hello, if the matter is not one that affects the public interest (e.g. antitrust, consumer-related case) then once the court has ruled then it is a private matter between the parties and it is up to them to decide who is included or not. Unless there is some issue still pending befroe the court then the court will not know or care about it.
the terms of the agreement, and parties included, are at the discretion of the parties
as long as the terms of the agreement do not violate the rights of the other parties as set forth in a court order etc.
also you mention stipulation of dismissal which suggests the case is still pending, the parties can agree to dismissal and file it with the court, such stipulations are typically granted as long as it doesn't adversely affect the public interest etc....the stipulation need not cover all named parties unless it is a special situation where the court deems it unfair/improper to exclude the party, but that is an uncommon situation
let me know if that answers your question
