Got a few small issues,

1. Front passenger side light is foggy compared to the crystal clear driver side, how do i fix this? Is this caused by a crack?

2. My passenger side rear bumper is not in line with the taillight anymore, is this a bumper clip issue?

3. The inside of my taillight is peeling, how is this caused?

Final question,

All of these started happening after the insurance company fixed the car, but this was around 9 months ago, would this be because they did not do a proper job? or is this just normal wear and tear and would not be covered if i took it back to them?
