2001 Ford Focus body & structure problems

Driving ford focus slowly in snow,a jeep spun out of control hit the drivers side front of car spun around and hit us again from the rear.airbag deployed and it my passenger full in face. Damaged her face with chemical burns and created a coroidital tear in her eye that is permanent and permanent vision loss in one eye. The impact of the airbag jarred her brain and she now has a brain injury called chiari malformation,

The latches on three of the doors either do not latch which makes the door fly open or it latches and doesn't open, after inspection the latches are so corroded with rust that they do not work at all. Before I realized that the door wasn't latching I had a propane tank for a grill in the back seat when I made a right hand turn and it hit the door and the door flew open and the tank went flying down the street and almost hit a pedestrian.
