Simple selective file sharing on a network

Hi - At home I have six PCs on a network.  I have a folder on my PC which I want to share with four of the other five people.  None have login access to my PC.

When I set the access on this folder to "Everyone", they can all access the folder.

But I want only four to access the folder. How do I tell Windows to allow for these four only, when they don't have login access to my PC? I cannot give them login access to my PC.

This is a very basic and simple question - it is not a complicated situation.

Thanks to all!
