You can buy CALS by computer or user.  If you have more users than computers, it makes sense to buy it per user.  Also, you will have to buy 2008 cals and have them down graded for 2003, as I don't think that OS is supported anymore.

I know that, but when i buy 3 win server license  and get 15 CAL with them, that cal are user or device cal ?

If i want that all users access one server in the same time, 15 CAL's from win server license is enough or?
If you have 15 users, yes, they can all access the server.

It should say with your purchase if its user or device, typically it's user cals.  Also, I only use Cals on servers that have AD on it, not on any storage or file servers.

CAL are per user accesing SIMULTANEOUSLY. If only 5 users are accessing to server, you only need this 5 CALs.
CALs are NOT for concurrent use. They haven't been that way for a very long time. User CALs are assigned to individual people (not username). Device CALs are assigned to a single piece of equipment. When you get your servers with the 5 CALs each, you decide what kind of CALs they will be. So, with 3 servers you will have 15 CALs total, which will may or may not be enough, depending on how many people you have and whether or not people access any of the servers from devices other than the 12 computers (such as smartphones, VPN connection, etc.)
