Can I create a new e-mail ID other than my existing one? Like for examp ... ANZ_411@iCloud.com

Each iCloud account has only one email main address, which can't be changed. You can, however, create up to three alias @icloud.com addresses to use which won't be a separate account, but will receive email in your current iCloud inbox. This article explains how to create an alias: http://support.apple.com/kb/PH2622. (If you create an alias address, it can't later be used to create a new iCloud account, moved to another account or reactivated if you ever delete it.)
