Edit in LR Clas out of Adobe cloud

Enable syncing in the Classic catalog (click on the cloud icon top right of the Classic screen and click Start Sync). When syncing starts, Classic will automatically download ALL the images that you have stored in the cloud to a local hard drive (you cannot pick and choose which images to download). The default location for the downloaded images is on your system drive, though you can elect to change the location to a different drive, and additionally you can choose to have the downloaded images stored into one of the standard date-based folder structures.....you might want to make those changes BEFORE you enable sync. You can find the options on the Classic Preferences>Lightroom Sync tab.

If you don't want to enable syncing in Classic, the only other way to get images out of the cloud and into Classic would be by exporting "as original" from the cloud to a local hard drive, then import the exports into Classic. Note that doing it that way does not allow edits that you make in Classic to sync back to the cloud.
