I received this small, potted plant at my father-in-law's funeral in 2016. This makes the plant especially dear to me; however, it has grown enormous in the last 6 years. It doesn't help that I live in a very small house. Would this plant live and thrive if I were to transplant him to the ground?
No, unfortunately. Not even close! This is a tropical to subtropical species, so it will need to remain in container.
You can divide them once they produce offsets. Give away larger plants, and keep the babies. I do this with some of my larger plants that are important to me. This allows me to keep smaller versions of it, without it exceeding the space that I have allotted.

I purchased yucca stalks or poles from blooms and branches and they were infested with these tiny green worms inside them. I had noticed the insect burrow holes on the sides of the poles / stalks prior to cutting them in half to investigate if that helps any. Please help me identify these little things.
The most common tunneling critter of yuccas is the yucca weevil but those larvae are grublike. This could be something that burrows during storage of the poles like a wood worm. I think I would be asking for my money back from Blooms and Branches.
My Yucca plant has grown and is almost touching the ceiling
Do you want to shorten it? Here is how:
I am in central Texas and this past winter was nothing like I can ever remember. We have a rather large Giant Spanish Dagger and a lot of the leaves are still in tact with some yellowing. On one particular side, middle, towards top, the leaves just pull off with a light tug. Most are green but still just pull off. Should I pull off all the ones that are loose? I have trimmed the leaves at the base that were yellow. It is over 20 years old and I want to save it. Even if it doesn’t look good for now. I just want to know the proper way to trim it without distressing it further.
You did the right thing removing the yellowed leaves at the base. This article should help:

That looks like the Yucca-leaved Beschorneria, or Beschorneria yuccoides.
Can I just cut them off and plant elsewhere? Sadly no photos available due to the collapse they hang over the lawn,hope you can help
You can stake those up and they should be fine till the blooms fade, then you can cut the spikes off and discard or compost.
