Not milk I don't think Kate, but the rest yes fine
And I agree, 4 meals a day probably.
Just google 'feeding 8 week old puppies' and you will find all sorts of good information. And do you go to the library, I used a couple of books for reference on all sorts of things.
Minnie never was a nipper, but a high-pitched 'ow' and looking hurt will often stop them in their tracks. Some puppies are dreadful, next door's little 'Jug' (pug x Jack Russell, ugly little thing!) would sink her razor-sharp teeth in straight away.
You would do well to get a baby gate (freecycle should get you one), or rig up some kind of barrier, so you can confine him easily within one room/part of a room. It's really not good for puppies (or for you!) for them to have the run of the house, or even the ground floor
But, be very careful that it's not something you will have to step over, you can all too easily trip on either it or him.
