Hi there Rita,
Ok, first, for the DF, you don't wake the LO's up, you do it while they are asleep, so pick him up gently, do this with the ligths off, the point is that he DOESN'T wake up, so to give him the bottle you are going to take advantage of their suclikng reflex, so touch his lips gently with the bottle, and introduce it into his mouth, he will start sucking.
And as for him waking up at 5am to feed (with or without the DF) what you do, is feed him just enough to hold him till 7am, and put him back to sleep, then set your alarm clock to what ever hour you want the day to start (7 or 7:30) and then wake him up at that hour, and feed him again.
Hope this helps
