We have 4 EV archiving server (1 Email and 2 File archiving) and EV DB servers, all of them are running Windows server 2012 R2. Now we are going to upgrade the OS to Windows server 2016. my question is that can I upgrade the OS one by one (maybe upgrade 1 server per day, total 4 days) or I need to upgrade them at the same time?

Since you are just upgrading the OS and not EV you should be able to upgrade 1 at a time. The EV version does have to be 12.3 to support 2016 so that would have to be upgraded first on all servers if not already at that version.
