There are 3 sets of data and I need to use exponential fitting. How to get a set of coefficients to satisfy the best fit to the three sets of data?

If they all follow the same model, just concatenate the 3 data sets and fit them as a single set.
If each data set has a different set of parameters. Just perform 3 separate fits.

They have the same x coordinate.

Not relevant. Just make 3 copies of the x-coordinate vector and join them together.
