I don't think it is possible for more than 3 users. Permissions and ownership of files is an old thing in Unix. For 3 users you can do it like that:

Set permission to 754
Set ownership to user A and group G
Create user A in group G
Create user B in group G
Create user C not in group G

Then A will have read, write and exec right
B will have read and write
and C will have read only.
