We analyze the recent STAR collaboration results on net-kaon fluctuations in the framework of the Hadron Resonance Gas (HRG) model. Our purpose is to extract the freeze-out temperature and chemical potential as functions of the collision energy. In our HRG model, we use the complete hadron spectrum from the latest PDG list. These results are compared to the freeze-out parameters obtained from a combined analysis of net-electric charge and net-proton fluctuations. At the highest collision energies, kaons need about 10-15 MeV higher freeze-out temperatures than the light hadrons. Predictions for moment ratios of the net-Lambda multiplicity distribution are obtained along the freeze-out lines. Lambda fluctuations are sensitive to the difference in the freeze-out temperatures observed in our analysis.
