Strange/unknown apple ID's on my phone

I recently had to restore my iPhone and it keeps asking me to sign into the iStore with a bunch of different apple ID's that I don't know. I don't know how this happened and no matter how many times I cancel or skip it keeps popping up at all times completely interrupting any other app I may be running at the time. If there is media on my phone that belongs to a different ID, how can I track it down to remove it?
