Got 2 AD sites  Site 1 is where the autodiscover would point to.
But both the sites can be accesses by seperates web mail url's
So I if I get a single SAN certificate which has the following names. Can I use it at both sites
server1.domain.com
server2.domain.com
autodiscover.domain.com
webmailsite1.domain.com
webmailsite2.domain.com

Yes you can.
But you have to provide the documents proves that both domain names are registered under your name/company name

Buy certificate with 5 SANs as 1st SAN will be your common name.

apart from that if your internal domain name matches any external domain name which is in use over internet.
Then it is very difficult to configure

our internal AD domain is  company.domain.com.
and we just have one email domain
in order to use both sites, you have to include the name of each site in your SAN Certificate, for example if you will access site one using https://mail1.domain.com, and site2 using  https://mail2.domain.com in this case you SAN Certificate hate to include both : mail1.domain.com and mail2.domain.com.

so having multiple entry to your exchange orgnization require multiple names to be in your SAN Certificate.

GOOD LUCK

--->our internal AD domain is  company.domain.com
One client installed his AD given name a name 'nsc.com'. Here this 'nsc' is his company name short form but nsc.com is registered under another company. Finally he end up in changing the internal domain name to 'nsc.local'

-->and we just have one email domain
If you have only one domain then buy one certificate with 5 SANs
yup what ur thinking is correct
I think I can just use single SAN certificate at both the sites as I have only single email domain.
one certificate which has all the SAN entries will do :)
