If you're talking about food yes, and the only way to do that is if you go in for employment purposes. If you go in just to get food you can only do it once a year but if you go in seeking help with employment such as writing a resume or whatever you can go back more than once I'm not sure the frequency though
Depends on the situation. You may get food only once a year but if you are unemployed and job seeking you may go more than once. They will even help you write your resume.
Yes, if you qualify for it.
