I had a raised bed of 5yo asparagus. We were hit by an EF4 tornado in late March that destroyed our backyard and gardens. Our asparagus was in good shape until we had to have major dozer work and for some reason the asparagus bed got dozed to the side of our yard along with a pile of tree trunks. The asparagus has popped up again, but this pile of trees has to be removed next. I need to know what to do with my plants/roots. Can I remove the whole asparagus plant to a new bed or dig up roots after trimming back soon? This was probably 4-5 dozen plants, just starting to really produce. Thank you for an answer.
Yes, transplanting them will be a good option. This is best done once they go dormant, though.
Here is an article that will help you to do so:
Spring 2020 I planted some three year old asparagus crowns. They were not harvested but cut back in early November and covered with a top dressing for winter. New spears are already showing. Should I leave them or cut back again?
Leave them to develop foliage. These articles should help:

I planted asparagus several years ago, maybe 4? Last year I saw a few stalks less than pencil lead diameter. I let them go to seed. I don't remember seeing anything but fronds in the years before that. Should I just give up or keep hoping I may get a stalk or two to actually pick?
Read through these instructions and see if your bed was built the best way to produce asparagus. If not, you may want to start over, but it takes three years before your first harvest. The bed needs 8 hours of full sun, plus well draining soil.

My asparagus emerges from the ground in very thick stems- what can I do to make them slender and edible?
Thinner asparagus is often tougher than thick, and has been touted as "gourmet" due to farmers' need to promote it. Thicker asparagus has more moisture content and is normally more tender. If your asparagus is tough, you can peel it like you would a carrot to remove the tough outer skin, but skinnier stalks are not necessarily the answer. You also may be growing a variety that's thicker.

My Asparagus plumosus is trained on a trellis. It is taller than the window it sits in front of now. Will the lower part getting light be enough for the whole plant, or will the top (now in shade) suffer?
They don't need direct sun so it should be fine. If the leaves turn yellow and drop you will know it needs more indirect light. Here is more:
