Photo sharing

Stop sharing an Apple ID. They are not made to be shared, and that is why you are receiving data from the other devices. It will just continue to get worse. If you are a family member sharing, then have the head of the household look into Family Sharing, Set up Family Sharing - Apple Support and you need to create a new Apple ID for yourself. In the meantime, go to Settings><yourname>iCloud and turn off Photos. This will also have an affect on any photos that you are taking and saving into iCloud as well.

You may get better and prompt responses if you may kindly provide the iPhone Model that you have and the iOS version if it is known to you.
