i have 3 devices sharing the same Apple ID. If I use icloud backup then is it possible that 3 devices have their separate back up so that when I restore 1 device from iCloud, it just downloads that device content
Yes, each device will have its own backups out there on iCloud.
Be sure to provide a unique name for each of your devices that you are backing up to the same iCloud account under Settings>General>About>Name. Then, when you back each one of the devices up, it will be labeled with that name in the iCloud backup list.
If you then erase one of your devices, and restore that device using iCloud, you will get a list of each of the backups available that can be selected to back up your device. Select the most current one with the name of the device you are restoring.
