The one in the photo will survive. That soil is very, very wet, though. Looks to have caused an infection. I would care for it the first year in container. This can help to get it up to size before planting. You will want to treat with a fungicide, as well.

With a severe pruning like this, your tree may need a period of time to stabilize. If it looks healthy at 2 feet and is growing a new canopy, there's a slight chance it will bear fruit, but I wouldn't plan on it for a year or two, maybe longer. A rule of thumb is to prune only one-third of a tree at a time. This article may be helpful: https://www.gardeningknowhow.com/ornamental/trees/tgen/damage-from-over-pruning.htm

Make sure your plant is in well-drained soil. If the roots are sitting in wet soil, they can rot and create the same kind of effects you might see in a plant that's underwatered. Check your growing conditions with this article:

With, occasional, pruning of the top and root pruning, you can keep this manageable in container. You may prune to your desired height, but it is best not to take more than 1/3 of the whole tree at one time. I would cut it back by 1/3, and cut out some of the larger roots and repot. Try not to break all of the finer roots when doing so. It is ok to lose anchor roots, but the finer roots feed the tree. Try and keep a good portion of them intact. Make sure that your tools are sanitary to avoid causing disease. Once you establish the first pruning, all others will be easier, and you may not even need to do a hard pruning again.
