Buddy,
In Unix, the users have been characterised into three groups:
Owner (you)
Group (a group of other users that you set up)
World (anyone else browsing around on the file system)
So you can put the users according to your conditions. Once this is done then u can provide permissions to those groups as a whole which will equally be applied on the users inside it.
This is the only way. We can't give permissions to users individually.

bos_setrestricted
BOS_SETRESTRICTED(8) AFS Command Reference BOS_SETRESTRICTED(8)
NAME
bos_setrestricted - place a server in restricted mode
SYNOPSIS
bos setrestricted -server <machine name> -mode 1
[-cell <cell name>] [-noauth] [-localauth] [-help]
DESCRIPTION
The bos restricted command places the server in restricted mode. This mode increases the security of the bos server by removing access to a
number of bos commands that are only used whilst configuring a system.
When a server is in restricted mode, access to bos_exec, bos uninstall, bos install, bos create, bos install, bos delete, bos prune is
denied, and the use of bos getlog is limited.
CAUTIONS
Once a server has been placed in restricted mode, it may not be opened up again using a remote command. That is, bos setrestricted has no
method of setting an unrestricted mode. Once a server is restricted, it can only be opened up again by sending it a SIGFPE, which must be
done as root on the local machine.
OPTIONS
-server <machine name>
Indicates the server machine to restrict.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see
bos(8).
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The bos command interpreter presents the ticket
to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see
bos(8).
-help
Prints the online help for this command. All other valid options are ignored.
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on the machine named by the -server argument, or must be logged in as
the local superuser "root" if the -localauth flag is included.
As noted above, this command cannot be run against servers which are already in restricted mode.
