If you keep it compressed, it will eventually cool down, but stay compressed.

If it's a solid in that state, will it remain a solid if you remove the container?

I think it’s still an open question if it is metastable (like diamond>graphite), but it definitely wouldn’t be stable.

Depends. If you remove the container quickly, then it explodes. Dong it slowly, some of the material evaporates and thus cools the rest, so that you can end up with piece of ultracold solid. But it will most likely not have same properties as the original material.
