Question

My icloud account does not sync with my iphone 4S. My contacts do not turn up on icloud and I do have "contacts" turned on in my phone.

Answer 1

Unchecking them won't help, it will only hide them from view.  The issue you're running into is that iCloud doesn't sync contacts from non-iCloud accounts like your exchange and Yahoo accounts.  In order to sync these with iCloud, you would need to copy them to the iCloud account and then disable contact syncing with these other accounts.  (If you didn't disable contacts syncing with these accounts, you would see duplicates of these contacts on your phone -- one from the external account, and one from iCloud.)  If you want to do this, do the following:
Go to Settings>iCloud, turn Contacts to Off, choose Delete from My iPhone when prompted (any iCloud contacts will still be in iCloud).
Download the app My Contacts Backup.  (If you have more than 500 contacts to transfer from your other accounts you will need the “Pro” version.)  Use the app to back up the remaining contacts on your phone (from the other accounts) as a vCard attachment to an email that you send to yourself.  Confirm that you have received the email before proceeding to step 3.
Go to Settings>iCloud and turn Contacts back to On.
Go to Settings>Mail,Contacts,Calendars>Default Account (in the Contacts section), and confirm that this is set to iCloud.
Go to Settings>Mail,Contacts,Calendars…tap your Yahoo and your exchange account and turn off contacts syncing with these accounts.  This will remove the contacts from these accounts from your phone.
Open the My Contacts Backup email and tap the attachment to import the contacts from these accounts back to your phone, and to iCloud.  All your contacts should now be in iCloud and be visible on icloud.com.
