Airbag fault light on

Hello its me again im just going to put all my codes on one thread to see if anyone can help me : Engine malfunction, airbag fault, seatbealt system restraint fault, engine oil below minimum ( i took it to get fixed because it was leaking all the oil really fast and all the coolant also but it only worked for like 3 weeks then it came on again. The low coolant light never came of to begin with, so now both things are leaking oil and coolant. Parking brake fault . Also my driver side window does not roll down it says its not working ????? Too many problems
