how do i add a second icloud account to all three of my devices without changing apple id

Your icloud account is tied to your Apple ID. Please see this discussion for some info:

One apple account with two icloud accounts

Please note that any purchases are tied to the Apple ID used to obtain them and they cannot be transferred, so if you want to create a separate Apple ID in order to get a second icloud account, you can do that - just remember to sign into your other ID when you want to update/buy/deal with the app store or iTunes.

Welcome to Apple Support Communities

• On the iPhone, iPad and iPod touch: Settings > Mail, Contacts and Calendars > Add Account > iCloud.
• On the Mac: System Preferences > Mail, Contacts and Calendars > + (at the bottom of the sidebar) > iCloud.

Note that a second iCloud account may not have the same features as the main iCloud account

There is NO one line that states Mail, Contacts and Calendars. There are three separate lines for each.

I have continually tried to remove my personal gmail account from my work phone and it needs another iCloud account to replace it. That is where my issue is. Every time I attempt to create an iCloud account it suggests that will be my NEW Apple ID. I do not want to change my Apple ID; I just want another iCloud account.

I am very confused and just want a second iCloud account for work use.

Thanks
