2014 Cruze. Turbo. Won't turn over. Codes p0171, p0420, p0442 and p0496

2014 Cruze, turbo. Not sure from where, but oil leaking passenger side and has everything behind the engine and underneath the car, covered n oil. Someone said oil pan so I tightened it up. I have been having trouble starting it after I get gas. But would eventually start. Well few days later, I Ran out of gas cause I'm an a&&hole. Got gas and when I tried to start it, the battery slowed drained and then nothing. Tried to get a jump. At first, it acted like it wantin to start but engine was knocking so I stopped trying. Towed it home. Ran codes. It did have codes for camshaft knocking and another one but I forgot to make sure I put gas cap and the oil cap back on properly before I tried to jump it. Cleaned and put caps on correctly and I got them codes to go away. Still left wit 0171, 0420, 0442 and 0496. I've read could b purge valve, o2 sensor, maf sensor or map sensor or even dirty fuel filter. Any suggestions on where I should start, which sensor mayb? Ty appreciate any help I can get
