So if this is not an appropriate environment for my cacti, what is the best thing that I can do?
Wow! What a nice collection were put in the bottle! I believe I recognize one of them
. And it would not be amenable to the growing conditions in a terrarium. I only see two plants with a lot of sunburn. Personally, I think they both might recover and grow well given time and a good environment.
For starting, if that were mine, I'd remove all of them and just lay them down on a paper plate or something out of direct sunlight and let them dry for a few days and look for any rot they may have before I put them each in their own small container. Containers with drain holes (essential for these type plants) and fast draining potting medium. After that, if there was no rot evident, I'd wait a couple of days before giving them water. Everything I see there will want a lot of sunlight. I suspect the bottle acted somewhat like a magnifying glass causing them to burn more than they would have if they had been out of it. I would move them into more and more light until after a week or two they were getting six or more hours a day of sun. That's based on outdoor conditions. I don't really keep mine inside, but if the sunlight were coming through a window I'd expose them to the light a lot quicker. I haven't found many plants burn when the sun enters through a window, but window conditions often don't let a plant get a sufficient amount of sun. Guess it all depends on your particular situation.
