Use the rule generated by NonLinearFit to substitute into your vector:
rules={a1 -> 0.00400772472374540367, a2 -> -1.90417580406264459*10^-6,
a3 -> 499088.922439139537, a4 -> 1.31534993678125777*10^-9,
a5 -> 7728.37550019371821};
desiredVector={a1,a2,a3,a4,a5}/.rules
Done this way, the variables a1, a2, ... remained undefined, so you can
re-run the Fit routine without conflict, and pick out the elements of
desiredVector[[ ]] as needed.
