Licensing is difficult, so you may want to double-check with the vendor to be on safe!
Here's how I understand Windows 2012 licensing.
In a Windows 2012 standard license we can have only 2 VMs; so in one ESXi server(of any sockets) we can host a maximum of 2 VMs;
That's not quite correct, the a Windows 2012 Standard edition license only covers 2 sockets.
Let's assume you have tree 2 socket hosts, and 6 VMs which can be migrated (up to 6 VM's on a single host).
In this case you either need to have a 2 socket Datactenter license for each host, or do peak licensing with the Standard edition, i.e. have 3 Standard Editions for each host.
