Can you get a water testing kit to test your water yourself? They are a little costly, but are extremely well worth getting.
Also, are you able to get ahold of any Tetra Safe Start? That seems to be the starter of choice. Tetra Safe Start will add organisms to your tank that will help your cycle through faster.
As far as temperature goes, 24-28 C is fine. I keep my tank around 27-28 C, but I have warm water fish. Mollies are fine with cold water, but some sicknesses can be cured faster in warmer water. You're probably fine at 24-25 C.
Do you have any aquarium salt in the tank? Mollies can live in fresh water, but they seem to do better with a little salt in there.
Also, I agree with everyone else about how many fish you have in there. He sold you _way_ too many for a tank that size. Usually we assume "one inch of fish per gallon" as the loose, general rule. Mollies will get to be around 1.5-2" each. In an 8.5 gallon tank, that's 4-5 Mollies living comfortably.
You can get away with more, but it's a challenge.
Fish are a challenge to get started in. But once you have learned the basics everything gets better. I promise
