Prius Prime 2018 Plastic Parts wondering where they should be snapped in

I was fixing my Prius prime myself and now I have these plastic parts that needs to be back in place. But I just can't figure out where they exactly should be placed. It would be great if anyone help explain how/where I should put them back.

Thanks,

 

Sorry that I didn't explain well when posted the thread.
I thought that I took the plastic parts from the both sides (Left and Right) of radiator. Now I don't know where they go back on. I wonder if anyone can give me the advice on this. Thank you.

 

Thank you for trying, sylvaing. I will try to figure out myself once again.
