For google drive you can do two things:
1. If you get to a gdrive link that has maxed it´s quota, you can save it to your drive. Then you go to your drive, right click on it and select where it says to make a copy to your drive. Then you have unlimited download quota for your own drive as it is now, "your file." You can add as many as you can fit in your gdrive (copy)
2. You can download them one by one, or you can install on your PC the Google Drive Backup and Sync tool, and you can leave that running and download your entire drive in 1 single shot.
