Publishing IOS 4 Screenshots Devices Conditions

Hi I please I need help, I m almost publishing the App in IOS but I need the Screenshots in 4 Apple devices, First of all, How can I do if I don’t have them?. Second, What happens if I upload Screenshots with Ads?, Third, I need to know if can I compress the images with photoshop before upload them.
It is mandatory to upload the app review? Can it have ads? Would be any problem if I use photoshop to delete Ads in Screenshots and App Review?
And finally, Can I upload iPad Pro Second generation Screenshots in iPad Pro Third Generation section?
