I took it home and started watering and misting it, and a new tinier fern sprouted from the roots. I want to re-pot the smaller one and get rid of the older one, but I don't know if it's dead or dormant. What should I do?
Unfortunately, your photo did not come through. I am unable to see what the situation is.
If the roots have not, completely, filled out the container that it is in I wouldn't recommend repotting it.
If the plant is rootbound, then you will need to cut away much of the root system, leaving only about the same size as the small plant. This is not the preferred option. It is best to leave it in one container for as long as possible, but it may be necessary depending on the root situation.
Here is an article that will help you with the care of the fern:

My Boston fern is very old and when it is growing well produces many "hairs". Should these be trimmed? How often? What is the purpose of the "hairs"?
These aerial roots can be trimmed away with no effect on the plant.

I'd like to actually see how to divide root-bound Boston Fern.

This is a 1 year old Boston fern (photos attached). It’s an indoor fern, and it sits near my window with west facing light. It is a cold climate (Canada) so it’s a colder sun. My fern currently has very few leaves. I’ve been trying not to overwater it, and it sits on a tray of pebbles with water for humidity, but I cannot get it back to “full bloom”. I don’t want to throw it out but I’m worried it’s beyond saving! Any advice would be so greatly appreciated.
There are so many possibilities here - and Boston ferns just do this sometimes.
I'm wondering about your soil. You may want to repot the plant following the instructions in this article:

and check your growing conditions here:

It may have a buildup of salts from fertilizer. I think it wants some fresh, well-draining soil. It also may not be quite warm enough in front of the window. You might try a south facing window.

It sounds like an infection in the soil. Make sure that the soil remains moist, but never wet or dry. It should fluctuate, slightly.
From here, you will need a fungicide, and to keep a close eye on overwatering, or saturated soils. This can suffocate plant roots, leaving them open to infection.

I inherited a plant 12 years ago when my mother died it actually belong to my grandmother. My friend say it is a Boston fern, but it doesn’t stand upright enough, in my opinion. I’m wondering if it’s a Christmas fern or a Ebony spleen wart? I will admit it is dryer and yellow than normal as 2020 has been difficult with getting separated moving twice and COVID-19. Thank you for any assistance you may provide.
It looks like Boston Fern but it may be attracted to light and thus grows like that. I had one that was hanging and growing more towards the window as it was less exposed to sunlight on the side away from the window in that dark room.
