Accidentally merged icloud data from multiple phones

Hi all! My iphone was stolen last week. Thankfully I had everything saved with iCloud (not backed up on my computer, however). In the meantime, I borrowed the 2 older iphones, which had old personal data and photos still on the phone. I signed in with my apple ID. Now a combination of their photos (and other info) and my information are merged with my iCloud. Is it possible to disentangle this information? Thank you for any suggestions!
