Group Tour

We are 10 family and friends doing a group tour in Nov. I plan on applying for 6 applications (the others already have (or will later apply for) their visas. Our travel agent provided me with an itinerary for all 10 of us.

I will be applying for my wife and me, a family friend, and 3 sons (one of whom is a minor). Is it possible to package our applications and provide one itinerary with all our names listed? Or do I need to make copies of the same itinerary for each application traveling in the group?

Also, I am told that all I need for my minor son (14 yrs) is a copy of his birth certificate with his application. Is this correct?

Thanks for your guidance.
