I keep my ferns in my garage because they are huge; they're 5 years old. This winter it got really cold and they did not freeze but most of the leaves turned brown, but are flexible as in still alive. Do I just do a clean-up on them (trim it down to new growth) and should they be fine? Should I do this as it gets a bit warmer outside?

Yes, once it gets warmer, you can trim off the brown foliage and new growth should take its place.
