1. Break up of salary will be available in your salary sheet.
2. HRA will be exempted u/s 10(13A), only if you're paying rent. Otherwise, the entire amount paid as HRA will form part of salary and will be taxable.
3. There is no criteria as such, that not claiming HRA will increase your basic salary. It depends upon the pay structure offered by your employer.
Please correct me if the above solution has an alternative view.
