Heat to evaporate. This is how a lot of people used to get sea salt; they would dig pits on the beach and let the sea water evaporate. Also, please use commas in your questions, it makes them a lot easier to read!
Yeah. Freeze it and then pass it through a coffee filter.
coffee is not a dissolved solute.. it's basically not a chemical reaction.. just distill the water out of it.. evaporate, capture and condense the water vapor. you'll then have water in one container, and coffee powder residue in the original container.

Yes, you can safely freeze coffee, in liquid form or in bean form, whole or ground.
Because it does not freeze or evaporate
There are plenty of crazy stories out there about chemicals added to freeze dried coffee. There is no reason for anything to be added to coffee when it is freeze dried; the entire point of freeze drying is that it preserves the product naturally. The process is: they make some coffee; they freeze it; they dry it. In short, whatever chemicals are in freeze dried coffee are only those - and exactly the same as those - found in "fresh" coffee.
Coffee typically takes about 2-3 hours to freeze in a standard home freezer.
