When you open .blend file all textures will apply automatically, if not make sure "textures" folder is located in the same directory as .blend file:

1. The scene contains 4 light sources which share configuration data, so when you change one light source the others will change accordingly.
2. The textures folder contains HDRi file, past it in your world shader to get the preview results (daylight renders)
