iCloud problem: Will I lose my files if I stop the iCloud download because it is stuck?

I am trying to restore some deleted files from my iCloud. Most are restoring and able to download. But the download is currently stuck and not progressing. If I stop the download, will I lose the ability to try and restore the files again? Or can I just stop the download and try again? I really do not want to lose these files in digital space!! I am terrified to stop the download. Has anyone had this issue?
