Yes, you need to add additional hiveserver2 on given hosts.

Hive doesn't have HA, it acts like load balance and distributes the connections.

in the "ALERTS" section I see "Manage Alert Groups" , "Manage Notifications" and 'Manage Alert settings" I don't see anywhere how to create new alerts ?

and how to assign the notification method to an alert ?

@Sami Ahmad

Use below link to create custom alerts which are not included in default Ambari.

As per my knowledge alters provided by Ambari are more than enough for daily operations.
