I understand what you are saying. My first experience with cats was two orphaned kittens that I bottle fed. They did exactly everything you described. It was hard to teach a kitten when you don't know how an adult cat behaves.
Some things that I learned that might help:
Get those plastic bendable straws and have them handy everywhere. Any time Train starts to bite or go for your food, give him a straw. I tied a few straws together to look like a spider---big hit. This redirects the unwanted behavior.
Blow air in his face if he goes after your food or bites face, then hiss at him and put him down. This worked well, gentle blows so not to take his breath away.
For chasing your feet, tie a string around your ankle with a tiny toy (or straw) tied to the string. You can tie a metal bolt or washer to the string to weigh it down so it will drag behind you. This redirects the bad behavior to the toy that you are moving around and not the feet.
One of mine will still dart to an opening door. Cat curiosity. Got to know what's on the other side. I just back out the doors so I can scoop kitty back away from the door and crack the door coming in to scoot kitty back in. They will get bored with this.
Scratching will be important before long. Have a couple of different textures handy.
Neutering will be important before long. Around the 6 month mark he will start to mature. If he sees or smells other cats around at night (you will not necessarily see what he does) he may start to spray to mark his territory. They 'can' get aggressive at that age too. Neutering will stop that.
My last orphan suddenly started changing at that age and I got him neutered ASAP. He is now back to his old sweet self.
You are doing a great jod. Like everyone said, you have to be the momma and teach him correct kitty etiquette.
It will get easier.
