DCPromo each DC while online so that they can update
the Enterprise AD when the last (only in your case) DC
of each domain leaves.
Proper demotion of the last DC will remove it from the
Forest AD.
(Technically the Domain Naming Master must be online
and available.)

Then you should have (additional) DCs for the domain
your are keeping in each site.

With a single domain (or even a small multi-domain
small forest) then all DCs should likely be GCs.

Yes, when "finished" with those domains.

Yes.

Only if it is done offline (when the departing DC-domain
cannot contact the remaining DCs, especially the Domain
Naming Master.)
In that case you use NTDSUtil but this isn't necessary if
you DCPromo is done with all DCs online and DNS
working properly.

The KEYS to removing them manually are below -- BUT
you REALLY should not need this:
NTDS metadata cleanup
Search Google for:
[ NTDS "metadata cleanup" remove DC Domain ]
No need to add either site:microsoft.com OR microsoft:
since the NTDS and other terms make it Microsoft specific
by itself.
Unless you WISH to restrict answers to the site:microsoft.com
for some reason.
[ NTDS "metadata cleanup" remove DC Domain site:microsoft.com ]
Key points to NOTE when doing the metadata cleanup:
You CONNECT to a WORKING DC.
You SELECT the missing/dead DC or DOMAIN
'Connect' and 'Select' are technical terms in this context.
