  Mixed species charge and baryon balance functions are computed based on
proton--proton (pp) collisions simulated with the PYTHIA8 model. Simulations
are performed with selected values of the collision energy $\sqrt{s}$ and the
Monash tune and the Ropes and Shoving modes of PYTHIA8 to explore whether such
measurements provide useful new information and constraints on mechanisms of
particle production in pp collisions. Charge balance functions are studied
based on mixed pairs of pions, kaons, and protons, whereas baryon balance
functions are computed for mixed low mass strange and non-strange baryons. Both
charge and baryon balance functions of mixed particle pairs feature shapes and
amplitudes that sensitively depend on the particle considered owing largely to
the particle production mechanisms implemented in PYTHIA. The evolution of
balance functions integrals with the longitudinal width of the acceptance are
presented and one finds that sums of such integrals for a given reference
particle obey expected sum rules for both charge and baryon balance functions.
Additionally, both types of balance functions are found to evolve in shape and
amplitude with increasing collision energy $\sqrt{s}$ and the PYTHIA tunes
considered.
