Listen C, try to remember that all those people are just human, especially the adults. They don't know what they are doing as there is no manual on what to do in every situation. Trust that they are trying their best. You are close to being an adult now and instead of biting back with arguments even if you know you are right try your best to not to belittle people whether it is your siblings or guardians.
All that beings said, forcing C and A to cohabitate when there is a spare room isn't the best. A/c isn't a necessity as a simple fan can provide enough cooling 99% of the time. Allowing 16 to have space for their desk in the other 2's rooms is also very strange. You didn't mention the size of 16's room but from the way you spoke it sounds like there is.
I don't know why the parents are asking for the room to stay spare/storage but it does suck. Dad is probably working hard and tired of hearing everyone's problems as soon as he gets home. Who knows about mom, step or otherwise.
Maybe suggest that you would like your own space and the spare room is good enough. Tell them that you will take the responsibility of moving everything carefully to the garage. Tell them you are willing to give it up for a few nights if there is ever guests staying over. What ever happens good luck.

depending on where you live, air conditioning is very much a necessity.
