5) iPhone 6+ 414 x 736 + @2x 1080 x 1920

Answer 1

Not everything is as sad as you wrote
1) At the moment, development for these devices is not practiced. It is common to support the current (iOS 8) and previous version (iOS 7) OS.
2) Similar to the previous answer, except for the iPhone 4S
3) and 4) the same during development
5) +
And that comes out with three types of screens.
As a rule, all this costs little blood when using Autolayout. And with SizeClasses you can live even with iPads.
PS Starting with iOS 8, Apple has been promoting the idea of ​​developing a fluid layout for iOS (size classes, autolayouts). Even the orientation of the device is abandoned and considered as a banal change in the size of the "window".
As for design:
Usually the design is drawn for one device (iPhone 6, the same), and it is cropped/stretched onto all the others. There are three types of arts used: regular(devices from point 1), @2x(devices from points 2,3,4,), @3x(device from point 5). But pictures are more and more abandoned, on the one hand, plane interfaces, on the other hand, iOS provides an excellent api for drawing many things programmatically. And vector graphics came to the world of iOS...
