Yes, but make sure that they are kinda the same age

Another guinea pig of the same gender. Guinea pigs are social creatures that get lonley if kept on their own. Most people choose to keep female guinea pigs in groups as you can have problems with boars (male guinea pigs) fighting. You can of course keep two or more guinea pigs of the opposite gender but unless you want baby piggies it's not a good idea. Hope it helped.
no
Only to another guinea pig of the opposite sex.
No. Mammals cannot change gender without medical intervention.
Guinea pigs are fine with towels, it doesn't hurt or annoy them in any way. Guinea pigs love soft materials so you should use them especially when cuddling them!
the opposite sex
NO they do the exact opposite they are way more scared of you
no... but if you don't want a lot of guinea pigs than i suggest getting two male guineas...
Chives are vegetables, so it should be okay.
You dont have to, unless you are keeping it with the opposite sex.
Yes, this is okay to feed a guinea pig. Not the whole bar but a small chunk of it is okay to feed. Do not do it often or the piggy can get fat.
Only if the paper has NO ink on it as ink has been known to be toxic to guinea pigs.
