Hello from a new Quaker Parrot owner in Austin Texas.

No, I would not push him either and if he is showing you that he is defensive then it is much better to back off and try later as the best way to teach them to not bite you is to not get bitten in the first place.

In your first post it sounded as if he was stepping up and then biting and for that I start off with just letting them know that they are causing pain by saying ouch or something similar, then I try such things as distraction and see if that works the last thing it to tell them " be gentle" or 'No bite" and step them off on the closest surface for a couple of minutes. This last works because they want to be on me they just need to understand when the bite is a bite. Any way it sounds like you have it in hand.

Quakers, especially the females, can be quite aggressive. But I am surprised Stormy is so distrustful of humans because she was handfed by your friend... but maybe all your friend did was just put the syringe in her beak and did not spend time socializing her.

Now, you might want to add some cooked whole grains to their breakfast because white steamed rice is nothing but simple carbs and that's not really good for them. I would also go easy on the cabbage and not offer it every single day, same with Kale which is very nutritious but also quite high in sorbitol, an indigestible sugar that can cause digestive upsets (I can't eat any myself). Broccoli is great though! And you might want to add more betacarotene rich stuff like cooked sweet potatoes - and let's not forget fresh corn (there is NOTHING they love best than corn on the cob!). I don't know what kind of small parrot seed mix you are offering but be careful with the sunflower seeds. Also, instead of peanuts (which are not really nuts), why don't you try walnuts, almonds, pistachios, etc? They are so much more nutritious and safer than peanuts...
