Questions about B2 visa

[wonderless]

I made another thread earlier but I also have another few questions.

1. I am at university and I will be living on campus (but I come home at weekends) so I selected the options to make my home address my main address. Which address do I put on my online form?
2. Also I am meeting friends who are going to the USA to travel. And I will be meeting them for 16 days. Do I need to put their names down in "who are you travelling with" question??

1. What you did is fine.
2. If you are really travelling with them to the U.S., you can put their names. However, if you are just going to meet them at some point when all of you are in the U.S., you don't have to put them.
