Pressure uder the rib cage, like fulness, gas, pale stool. Did ultrasound and blood test, all normal?

Get complete workup. If this pain is constant, a more complete work-up is in order. Whatever may be going on might not be fully present, or it may be just gas. Pale stool may point to some underlying illness or altered diet. At this point, a more thorough workup should be done with follow-up to make sure this is not serious, like pancreas problem (s). Keep in touch with your doctor.

I have minor pain at times & dscmfrt under right rib cage about 2 inchs fm front center of lower chest. Ultrasound & blood test are ok. Could it be gas?

Could be. If the pain persists for more than a couple of weeks or gets worse it would be prudent to see your doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

I keep having occasional pale stool: did abdominal ultrasound, did several blood test (for liver, pancreas and more) all normal. Could it be gerd?

No. Pale stools with normal labs and ultrasound usually are not worrisome and most likely represent rapid transit in the intestine. "gerd" or gastroesophageal reflux is an irritation of the upper digestive system often causing the symptom of heartburn and does not usually affect bowel movements.
Not likely. Gerd (gastro esopageal reflux disease), has to do with reflux of acid into the esophagus. This has heartburn, regurgitation, nausea, dysphagia, and bleeding, among other things. But not pale stool. Problems with the pancreas might do this. Pancreatic cancer can have clay-colored stools. Unless this presents with other signs and symptoms, it would be hard to say what it is without more tests.
