The $folders are usually from windows update, but they are also used for hiding folders for non-admin accounts. In Windows XP/Vista/7 you will see $folders in the C:\Windows. The ones for Windows Update can be deleted, and this will free up hard drive space and remove them from your Add/remove programs, but not from windows. Basically once you delete the folder, you will not be able to remove them through add/remove programs. One of the Windows update $folder you want to keep, I think it's $cat or something like that. It basically is a catalog of all the updates and speeds up finding updates you need the next time you run Windows Update.
The Windows.Old is there because you ran Windows 8 Upgrade. It's your old operating system, and is just there if Windows 8 borked something you have a backup of your windows folder. Once you have upgraded, have no problems, and do not plan on reverting back to your previous operating system just delete that folder.
I would suggest not deleting any $folders unless you know they are not needed. Some may be needed.
