iCloud backup

Hey guys,

So I am setting up my new iPhone and using my iCloud latest backup to get things started. I noticed a few concerning messages. One was:

"This iCloud backup includes purchases from the iTunes Store that were made with a different Apple ID."

and the apple ID was, ****

I don't recognize this at all. After i skipped this step, then another 3 unfamiliar apple id's came up. Did I get hacked?

Is there an explanation for this?
