1. I strongly suggest you don't try it. In pet stores, you may find rodent hanesses, perhaps even those labled for chins. But these can all to easily crush your pet! No small animal should be put into a harness. For one thing, chins are really jumpy animals, so trying to take one out doors will inevitably result in it jolting and getting it's chest crushed, or it will run off and you won't be able to catch it. If you need to transport it, use a proper rodent carrier.2. Chins can live up to 20 years. When you're in college, are you 100% certain your college ALLOWS chins? I don't know what you mean by 'make living conditions', but if you will be living in your own place, make sure a chin will not be a problem there either. Some roomates or landloards might try to evict you or something. If anything and you cannot take it with you, don't get one. All animals get attatched to their owners. And for all animals, being brought into a new environment is incredibly stressful. If you think you won't be able to keep it, and will have to rehome it, don't be selfish and think about what the animal will go through. There are also hundreds of homeless chins in various shelters and rescue groups, so you may be interested in adopting an older one that needsa home.3. It's better to get two or more same-sexed or neutred chins. In the wild, they live in large family groups of up to 100, so they are social. You should take them out and handle daily, even for a few minutes, but for all the hours of the day you cannot be with your chin, it will have companions and not be forced to sit there on its own. They are pretty intelligent, so they should have things to do or play with, which a friend provides.4. As far as I know, not much. Females tend to be smaller, but I have seen plenty of small males and large females too. Females also spray slightly more than males.

Go online and do a search on "chinchilla care" and get as many perspectives as you can. I strongly suggest you get books as well. And NEVER trust what pet store employees tell you. They are wrong so many times it's a wonder half their display animals are alive.
