haw many of each of the roles can I have, per domain, per forest?
try this command netdom query fsmo (it will show FSMO roles in current Domain) netdom query fsmo /d:Domain FQDN (It will show FSMO roles in other domain mentioned after /d:
the server which holds the FSMO role it cna be changed by few methods 1. go to admin option->users and computers -> select domain->rt click fsmo roles gives three tabs of domain fsmo role holder-> change from there. 2 for other roles go to admin option->use site -> forest level roles you can cchange in the properties of each fsmo role holder. 3. NTDS util will help you to see the roles and transfer
The server which holds the PDC FSMO role it can be viewed by few methods 1. go to admin option->users and computers -> select domain->rt click fsmo roles gives three tabs of domain fsmo role holder. 2 for other roles go to admin option->use site -> forest level roles you can see in the properties of each fsmo role holder. 3. NTDS util will help you to see the roles.
There is no releation between FSMO roles and replication. However Infrastructure master role replicate the cross domain group membership changes.

Domain naming master - rid
FSMO
In a Windows Server 2008 domain, there are five Flexible Single Master Operations (FSMO) roles. These roles are Schema Master, Domain Naming Master, PDC Emulator, Relative ID (RID) Master, and Infrastructure Master. Each role has a specific purpose in the Active Directory environment to ensure proper replication and management of directory data.
FSMO stands for the Flexible single Master Operation, there are 5 types of FSMO Schema Master Domain Naming Master Infrastructure Master Remote ID Master(RID) PDC Emulator Regards Anil Mahapatra
A forest in Active Directory contains a total of five FSMO (Flexible Single Master Operation) roles. These roles are divided among domain controllers within the forest: one Schema Master, one Domain Naming Master, and each domain within the forest has one RID Master, one PDC Emulator, and one Infrastructure Master. Therefore, while there is only one Schema Master and one Domain Naming Master for the entire forest, there can be multiple instances of the other three roles, depending on the number of domains present.
Windows 2000/2003 Active Directory domains utilize a Single Operation Master method called FSMO (Flexible Single Master Operation), as described in Understanding FSMO Roles in Active Directory. In most cases an administrator can keep the FSMO role holders (all 5 of them) in the same spot (or actually, on the same DC) as has been configured by the Active Directory installation process. However, there are scenarios where an administrator would want to move one or more of the FSMO roles from the default holder DC to a different DC. Windows Server 2003 Active Directory is a bit different than the Windows 2000 version when dealing with FSMO placement. In this article I will only deal with Windows Server 2003 Active Directory, but you should bear in mind that most considerations are also true when planning Windows 2000 AD FSMO roles
Active Directory in general uses a multimaster scheme for updating the directory databases between domain controllers, there are specific functions that can only be performed on specific domain controllers. These specific functions are assigned to one of the five FSMO roles, (pronounced "fiz-moe roles") which can be assigned to one or more Domain Controllers.
