That will confuse iCloud; some have mac.com me.com and icloud.com addresses but iCloud treats them all as the same account and delivers according to which the email was addressed to.  Different user IDs however will confuse the system.

You can add up to three 'email aliases' to your present account - these are additional addresses (not accounts) which deliver into the same inbox as the main account. (In fact it's a good idea to give out alias addresses, rather than the main address, because if they attract spam you can easily change them.) (New aliases can only be @icloud.com ones; @me.com addresses cannot now be created.)

You should be aware before you start that once you've created an alias you cannot turn that address into a full iCloud account, move it to another account, or reactivate it if you delete it.

More information on aliases here:

Alternatively you can create a new Apple ID and use it to open a new iCloud account which you can sign into in System Preferences (or Settings)>Mail, Contacts and Calendars. This secondary account can sync data between its own online account and your Mac, though it cannot use PhotoStream. Data entered in one account won't appear in the other online, though both appear in alongside each other on your Macs or devices.

Thanks, Roger...I was making a hash of that and decided I had better quit.

You can have more than one icloud email address without using an aliases, all on the same Apple account.

iCloud: About your @icloud.com, @me.com, and @mac.com email addresses

Depending on when you created your iCloud account, your iCloud email addresses and aliases may end with @icloud.com, @me.com, or @mac.com domains. Learn how these email addresses are granted.

Review these scenarios to see which one applies to you:

• If you created an iCloud account on or after September 19, 2012, your email address ends with @icloud.com. Learn more about @icloud.com mail addresses.
• If you created an iCloud account before September 19, 2012, or moved to iCloud with an active MobileMe account before August 1, 2012, you have both @me.com and @icloud.com email addresses.
• If you had a working @mac.com email address as of July 9, 2008, kept your MobileMe account active, and moved to iCloud before August 1, 2012, you can use @icloud.com, @me.com, and @mac.com email addresses with your iCloud account.

In each case, you can sign in to iCloud with either your @icloud.com email address or the Apple ID that you use with your iCloud account.If you created one or more email aliases for your account, be aware of the following:

• You can change or delete an email alias, but if you delete an @mac.com or @me.com email alias, you can't add it back to your iCloud account.
• You can't sign in to iCloud.com with an email alias. Sign in with your @icloud.com email address or the Apple ID that you use with your iCloud account.
