Fire Relief- We lost everything

My family lost our entire life tonight. I don't even  know where to begin to start so I'm starting here.. We managed to save all animals except for 2 cats, they suffered from the smoke inhalation. Myself, Son( 4 year old boy) Mother and roommate ( 60 year od gentleman) have lived there for 3+ years but too top it off, we had my brother ,his pregnant girlfriend and 2 cats staying with us for a month or 2 before a new baby and today was his 30th birthday. My furnace room caught fire and unfourtanly due to moving stuff around, etc etc most of our stuff but ALL of theirs,  my roommates stuff and ALL of Aaron's clothes are gone, :'( I dont know where to begin to replace this or where to live . Red cross has given us a hotel and food for 72 hours but then it's up to us. Where do I go? WHO do I call? I didnt have renters insurance so that's not a option
I NEED help. I NEED advice. I Dont even know where to begin.. all I can smell is smoke.
