can a datastore be on two machines?

Can a datastore be attached to 2 vm's? I have a datastore that i want to transfer to a Win 2012 server from a 2003 server. I want to do this with no interruption to users. Can I attach it to a second machine, redo the mapping and then shut down the 2003 machine?

Yes.

Yes you can, but there will be service interruption, because you will need to re-do the Server Mapping, and the server will have a new name!

Yes, there is no reason why a VM cannot access one or more datastores.

You may have a slow and fast datastore e.g. for SQL DB and Logs.

Perfectly acceptable.

The datastore is what is used on the host level - multiple VM's can reside on a datastore as each VM is individually housed in its own file.  In regards to attaching to a 2nd machine, if it's FC / FCoE that's a physical connection. iSCSI can be attached but it is not recommended that multiple machines connect to the same iSCSI target as it can cause data corruption.
