The answer is positive. Rational function of Jacobi elliptic function is elliptic, and for every elliptic function $f$, $f(z)dz$ is an Abelian differential, and integral of it is an Abelian integral. Abelian integrals can be decomposed into a sum of the standard elliptic integrals (of first, second and third kind), and each of them is a special function, one of those that you listed. This decomposition is an analog of the decomposition of a rational function into simple fraction. The algorithm of decomposition is described in all standard books on elliptic functions, for example,

I am sure that standard computer algebra programs do this.
