DNS, DHCP, Print (sorry), one acts as proxy (sorry) and one has some cloud ldap sync software on (again sorry)

I plan to promote a remote DC first (over a VPN) but not sure (from memory) if it will work as not in same site (based on exchange sp3 update in the past)

DNS is fine; that will be replicated over with AD once they are promoted

the site of the server to be promoted doesn't matter
as long as the site is defined in AD with its related subnet, i don't see any issues
exchange is more sensitive as far as having the schema master in the same site for updates, but AD only needs to be able to contact the server with those roles; doesn't have to be in the same AD site
