Getting contacts out of email and into iCloud

Someone wrote this advice to someone else: If your contacts are syncing from another email account, then those wouldn't be included in an iCloud backup. You can check for this in Settings > Contacts > Accounts.

So i look in accounts and i see 7 accounts including iCloud. I know that not all of my contacts are in iCloud. How do i move contacts from each of the email accounts into iCloud?
