What should be protected from low temps?

[TOMMYMIAMI]

So first cold front passing. Since this year's weather is really really strange, I wanted to check what should I cover or take inside, in the case we will get some severe cold nights here in South Florida. I am not concerned about tonight, the lowest will be morning with 53, but we may get some colder nights in December and January. I have never had such a variety and species as I do now, so I would appreciate any tips what should be protected from my collection and at what minimum temps? Also, does it get as cold on the 5th floor balcony as it gets at the ground? Many thanks. Here are my babies, and sorry for capital letters I did not know at the time when I started this, I will work on retyping it when time allows
