The short answer is: "None" See the answer for the question: Are canon t70 and canon eos rebel xsi lense compatible? The Canon AE1 takes FD mount lenses. All Canon digital cameras take EF lenses. They are not compatible.
Unfortuntely, No you can not use the AE1 Program lenses with Canon EOS cameras. They use different types of lenses, thus the diameter, connections and mount are different.
The Canon AE1 lens will not fit a Canon digital. You can buy an adapter that will allow the lens to work in manual focus mode on the digital camera.
With just the standard lens? Maybe as much as $40 if it's in pristine shape. They can be had on eBay for $20.
The Canon 60D uses an EF mount type.
To mount a Canon lens on a Nikon body, you will need an adapter ring that is compatible with both the Canon lens mount and the Nikon body mount. This adapter ring allows you to physically connect the Canon lens to the Nikon body, enabling you to use the Canon lens on the Nikon camera.
Old AE-1 lenses, which typically use the Canon FD mount, are not directly compatible with modern Canon DSLRs that use the EF or EF-S mounts. However, there are adapters available that can allow you to use FD lenses on Canon DSLRs, but these may result in manual focus and exposure adjustments. It's important to note that using such adapters may limit certain functionalities of the camera. Always check compatibility and functionality before purchasing an adapter.
The AE-1 lenses have Canon's FD breech-lock lens mount. They are not compatible with Canon's later EF lens mount. It may be possible to find an adapter, but performance would be lost, and the lens will not have the features of an EF lens. Best to save your money and get a dedicated lens, either Canon or Sigma.
No.
