Hi,
Does it produce brebas ?
If so I wouldn't prune this year. Or just one tip every other tip.
If it is 8' in height, I would let her untrimmed this year. More branches, more figs.
My personal limit is 7' - so at 10' of height in the Fall, I cut them back. This year I had to cut back my two bigger ones for the first time (Winter had been doing it for me every other year or so ).
You may want to cut remove the top central leader on each trunk to promote more growth on the side branches.
Root-shoots : either you want them, or you should remove them asap even during the season.
I would keep the 5 bigger (4 big, and one a bit thinner) trunks, and remove all the others.
Depending on what you want to do or not : I would cut the root-shoots flat, or pull them with both hands near the dirt as they may come out with roots.
If you want to keep them growing, now ( when dirt has thaw ) is a good time to do that. You can relocate them to (1 or 1/2 )gallon pots and make some experience at pot culture. Those pots would be your backup plan in case one year, the main tree dies. OR you could exchange them for other trees ...
Keeping the trees in check is important, but I don't think that we should trim them too often. My plan is to trim them every 4 years, no more. I want and really need to get a good breba crop... as some year, the main-crop can't ripen properly - here.
