First things first, you need to make sure she is separated from the culprit (i.e. dad). They can get pregnant again almost immediately after giving birth.
You can make a nest with something soft, like a towel or blanket inside a box. It is okay to touch and move the babies.

LBJ is correct, they can fall pregnant again immediately..
They need to be kept warm or they won’t be able to feed. Get a fleece blanket and cut it into strips, make sure there are no stray threads the bubs can get caught on. Form a nest out of some hay and news paper and sit the bubs inside together. It is OK to touch them. Mummy will only feed them once or twice a day and generally in private. You need to check for fat little tummies.. Because they are pray animals Mummy will spend time away from them between feeds and when they do feed it will be quick. Remove any water crocks from the cage and use a bottle, the babies can be moved about if mummu takes off when they are still attached and they will start to wander, it is easy for them to fall into a crock of water and drown even if it looks unlikely. Baby savers can be threaded around the base of the cage to keep them from falling out. I cut up the bases plastic of some eco shopping backs, three strips from each one and threaded it between the bars. . Your rabbit will be producing milk so she is going to need unlimited food for the next couple of months, everything, pellets, hay and greens. I would keep mummy in the cage with the babies for the first day so she will hopefully give them a feed immediately. Put a towel over the end of the cage so she has some privacy. She will feed them standing up over them bunnies do not lay down to suckle.

Sounds like her natural instincts didnt kick in. So you will need to keep checking the babies get fed.
This article instructs how to assist feeding if required.

I think making a nest as suggested should be enough. Being angora, you could possibly trim some of her fur to line it but I wouldn’t fuss too much. She’s been through enough.

Good luck!
