No, do NOT try to bottle feed them, especially not at this age. If the mom wasn't feeding them, they wouldn't have lived this long. When I bring in new rescue rabbits, unless they need medical care I leave them alone as much as possible for the first coupleof days to let them settle in. Whne you do start to handle them, do it gradually. Start just by touching them a little as they move around, and move up slowly from there to picking them up. If you jsut go in there and grab onto them all you will do is make them more afraid.
Rabbit rescue and care is very different from caring for cats and dogs, partly because a rabbit is a prey animal and therefore thinks and acts very differently from a predator like a cat. You may not ever see the mother rabbit nurse, because it is her instinct to hide when she does this.
