On a leaf spring made of some number of leafs, do each leaf has the same form as the master leaf?

If not, what is the percentage of change

really, the real answer is 'it does not matter much'.

On a common multi leaf spring, the major is some length/arch. If you break one leaf on one spring, all you have to do is cut it separately, find a alike substitute, and put it in. Once you tighten the center screw, that leaf matches the curve of the ones above & below it.

Now, if you break the 'main' spring, you most likely want to replace the assembly on both sides to avoid leaning.

no, each leaf has a different dimension and curvature to manage the loads and to be able to be stable on the road in corners

I just installed helper springs on a 99 GMC 1/2 ton and yes they were "bowed" about the same as the factory springs are
