How to create 2 icloud accounts with one apple id

Question

I would like to find out how to create 2 iCloud accounts using the same apple id. Currently, my husband's iphone4S and my iPhone 4 have merged contacts which we don't want, and when he texts it shows that it is from me.

You can't do that.  One of you will have to create a new icloud account with a new ID and connect the device to it.
TO GET DATA FROM ONE ACCOUNT TO A NEW ACCOUNT:
When connected to the account you want to GET data from, Go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off. 
When prompted choose to keep the data on the iPhone. 
After everything is turned off, scroll to the bottom and tap Delete Account.  Next, set up a new iCloud account using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On.  When prompted, choose Merge.  This will upload the data to this new account.
Note that this only affects the "Apple data" like contacts, calendars, reminders, etc.  Many third party apps also use iCloud to store data files there.  These files may be lost in the process, unless the apps also keep the data locally on the device.
NOTE:  Photos in the photo stream (if you use it) will not transfer to the new account.  It is advised that you save the photos to a computer before performing the account switch. 
CREATING A NEW ID:
Each user should have their own icloud account, otherwise they end up getting the same emails, contacts, calendars, notes, reminders, etc. - usually not what you want.  But if all have been sharing the same itunes ID, keep it that way, you can have different IDs for itunes and icloud.
If you already have another icloud account, and want to set it up on a device, then go to Settings>icloud, scroll to bottom of screen and tap Delete Account.  This only disconnects the device from that account, no data is lost on icloud.  Then enter the account ID that you want to use.
