If I have server1 that holds the primary zone and server2 holds the secondary zone.
In the Name servers I have Server55 and server66. Does that mean server55 and server66 should have a secondary zone on them or not necessary. if not what's the purpose of adding them under Name Servers tab.

    If you add a name server to the name servers list that server should be able to provide an authoritative answer for the domain in question.

    For example, if I had a domain called with the following Name Server list:

    I would expect that each of those servers host a copy of the zone In the traditional DNS model the server listed in the SOA for would be Primary, the rest would be Secondary.

    The NS resource record would normally contain all the DNS names for the DNS servers that are authoritative for that domain. So it should list both the primary and secondary DNS servers.

    which means there is in fact the same zone name  in the dns servers listed under Name servers tab, otherwise they can not be authoritative for the zone.
    In other words if I logon to any of the servers listed under the Name servers tab, and open their DNS console, I should find the zone name there. Correct?

    As long as you have configured the DNS servers in question as secondary/primary servers for that zone.

    What the the list of DNS servers in the NS records are doing is advising (the client )what DNS servers (authoritative servers) have a copy of the zone file  for that domain, but you still have to configure the zones in those DNS servers, this can be via zone transfer incase of a configured secondary server
