If you lost a passport then answer yes. I do not quite see how this can be a question. Are you asking whether you should lie on the DS-160???? Of course not! The two fundamental rules of dealing with immigration officers: 1) never lie 2) never offer information unasked. BTW at the interview they will want to see the previous passports.
I do not get this question. What additional documents? You have documents showing other sources of income, like a rental? In that case, you are running a (one person) business and so
If you are a business owner, enter an average amount of net income you receive from the business after expenses.
So I would enter the total amount you are getting a month from every source that you can back up with paperwork.
