Did you notice the flats on 2 fittings? Assuming this is not your issue...
Firstly, you really shouldn't have cut the tubing before removing your fittings. But now that it is irreversible. You will need to replace one fitting at a time and use the Radiator as a vice(support) of sorts. Make sure not to overtighten the fitting, but it needs to be snug because you will need to keep it steady when removing the compression rings.
This is gonna be real fun for you since you cannot put that Radiator in a Vice. Think "Tin Can" here. Easily distorted and wrecked should you attempt this. Get someone with some upper body strength to stabilize the Radiator, take a Rubber band/packing tape and wrap the compression ring and then try to remove it. If it's too slippery(often is the case with packing tape) then you will need a pair of lock pliers and you should be able to undo them carefully.
I used this method back when I had a bunch of Black Nickel fittings and had to do what you're doing. Of course those tubes weren't cut down to the length of what you have. So there ya go. Should be easy peasy.
