1. Bad breath problem may be due to tonsillar keratosis or chronic sinusitis. You should be examined for that. For time being, you can try any Chlorhexidine mouth gargles.
2. Question is not clear. If there is any swelling over base of tongue. Then you should consult an otolaryngologist in person.
3. This is normal. That is called nasal cycle.
