Is it possible to still have asthma with normal oxygen levels and normal chest xray?

Yes. If you are not having a flare of your asthma. If flaring, your oxygen level may lower as the flare worsens and your chest x-ray will likely show (if done) hyperexpansion of the lung fields due to air trapping.
Yes. Between episodes an asthma patient will usually have normal blood oxygen levels and chest x-rays. Someone with recurrent episodes over a period of years may have suggestive changes on an x-ray, but the findings are not specific to asthma.

Stick with 1 person. Sounds like you are shopping around for opinions. If you have chronic cough that is productive, there can be many causes. Working with one pulmonologist will help you get at the root of the problem. Asthma doesn't usually cause a productive cough, and most bronchitis is viral, so antibiotics won't work. Post nasal drip, allergies, chronic bronchitis, bronchiolitis, bronchiectasis, reflux, etc. Read more...
See below. You may have some form of interstitial lung disease, or an atypical pneumonia. Those frequently respond to corticosteroids but you may need more tests to pinpoint the diagnosis, such as ct, bronchoscopy, biopsy. That will allow to tailor treatment.
