I would think the DPD powder; TA titrant and acid and base demand titrants would still be good and also the cacium buffer (reagent 1 of the calcium test) as long as you let them totally unthaw before using them. (These last 4 are basically just solutions of sulfuric acid [TA titrand and acid demand] and of sodium hydroxide [base demand and calcium buffer].) I also think reagent one of the TA test would be good [just a solotion of sodium thiosulfate to neutralize chlorine]. I would dump the others and get new ones. Not sure about the CYA reagent but I suspect it would also be good after freezing. Richard, care to chime in here?
