I was just about to close PS, but here you go. I’m not sure if it is okay to post it, since I used psd by Diana as well, tho I did not use the Gradient Map for the second image. What you can’t see in psd is that for the duplicated layer I had applied Film Grain (settings Grain: 2, Highlight area: 1, Intensity: 1 ) Filter to it, sharpened it and set it to 30% 
There are more slightly different colorings you can get if you duplicate some of the folders and layers and play with opacity. There are also some layers I haven’t applied in second folder.
