Question

While in a folder with lots of files, one can select many and rename only one. This one will get the name NewName (1) and the rest will follow as NewName (2) etc..

Is there a way to use this algorithm?

I mostly interested in using WinApi methods in general. It is easy to implement this specific algorithm. I don’t know how to dig into explorer.exe and see what method it uses but probably it would be something reusable.

I mostly use c# but any language example would be accepted.

Not with a single function call, no. But you can loop through the files one at a time using SHFileOperation() with the FOF_RENAMEONCOLLISION flag to rename each file to the same target filename so Windows will generate its own unique filenames.
