British passport application for family

For the first time British passports I have applied online for myself as a main applicant and all my dependents including spouse. For sending passports and British citizenship certificate to the HMS Passport office, please can you advise if I should the documents separately for each applicant or I can send them together in one courier and in packet? Thanks and apologise in advance if I have not used the correct link?

Have all the online applications been given the same passport office address??

Each application needs their own documents in their own envelopes sent to the respective passport office each application states.
