BRAVO! Great way to grow at least three different figs in one hole. As the individual trunks keep getting thicker the cambium layers will start to fuse into one, composite-trunk. The tops can be trained into a nice rack of branches, which will bear different figs. Great job.
Also, using three or more of the same variety will ensure the same ripening and growing characteristics, but you will sacrifice the novelty aspect of the training, and braiding efforts. But still, it's a good way to increase the yield of your favorite fig without wasting too much space for individual trees. Braid and train, three, four, or five, e.g. "Col de Dames" together....and you got yourself a tree!

By the way....why can't Apples, Pears, Pawpaws, etc. be grown the same way? All these trees need pollinators for better yields, so plant different trees in the same hole, and braid/plait/pleach them. Why nurseries don't use this method instead of grafting to "create" trees bearing different varieties on the same tree, is beyond me. I think braiding is easier than grafting.
