Hi @Muzaffar1
How many machines you need - only you know the answer - it depends on what you do
As for the rest, don't get me wrong, but you are writing on internet forum, where people help other people for free, and in most cases are not from Microsoft 😉
So in order to advise anything to you - do some work first and let us know what are you doing, what issues you encountered, what did you try to fix your issues, and where need assistance 🙂
