As Throbert pointed out all(most) of the names of the above can be found on wiki, with pronunciation and transcription
However the hardest part is not to find/listen to the pronunciation but understanding and pronouncing it
For example: my name will be written in Russian as Артём. But for native English-speaker this name is basically impossible to pronounce, mostly because of two things:
1. There is no ё sound in English. I had to write my name either as Artyom or as Artem. Both are incorrect
2. Stress goes on letter ё but for English speakers it's weird and unnatural

So if I write my name as Artyom it will be pronounce something like Артиом
If I write as Artem it will be Артэм
Even if I pronounce my name to English speakers - most of them can't repeat it and some who can forget it in a day

So unless all names of the above will be written in Cyrillic all the time, I don't think it will be a way to force people to pronounce them correctly
