Welcome back to the Wefugees Community and thank you for reaching out to us.
If your friend does not have a residence permit yet, is he holding a "Duldung" (for instance after receiving a negative answer on his asylum request) or an "Aufenthaltsgestattung" (in a pending asylum procedure)? If one of those two alternatives is the case, he is entitled to receive "Asylbewerberleistungen" which he would need to apply for at the "Sozialamt" (how it is called in most of the cities). If you want to explain his location, we are happy to support in finding the right application form online and responsible office.
I hope this helps and please get back to us if there is any clarification needed.
All the best,
