@jahncrish That sounds so scary and frustrating for everyone. Sorry to hear your family is going through that. I am a pediatric dietitian who happens to spend a lot of time helping low weight babies. You may consider requesting a referral either to a dietitian or to a pediatric GI clinic (that is the specialty that usually handles low weight gain referrals)
Without knowing your brother personally, can’t make specific recommendations but can tell you I would start with adding sources of fat to meals (avocado, but butters, oil, butter, etc). That way, each bite he takes will be more calorically dense. Even an extra teaspoon of oil with each meal could make a big difference depending on his current size. Additionally, we sometimes look at changing the calorie concentration of his formula. You would need a dietitians close oversight on that though, so again, the referral would likely be helpful to you all.
Another consideration may be occupational or feeding therapy if he needs help learning to manage and swallow the food in his mouth, how to spend more time at a meal, etc. just some things to consider.
Good luck! I hope you guys find what you need to help him!
