It’s happening to most of my mother and children plants, but not all.
I'm seeing signs of overwatering stress. The soil looks very heavy with a high clay content. This will, often, lead to problems with agave. The soil is best amended with lots of sand, and some compost, to give it a much lighter texture. Unfortunately, clay soils can hold too much moisture under the surface.
Make sure that these do not get watered unless there is a very severe drought. If it rains often in your area, then this may be a battle for the remainder of the plants' lives.
It may be best to use biofungicides to counter the moist soil conditions.

I would like to know how to plant. As you can see there is no stem to the root. There are a few roots sticking out. Not sure what to do. Thanks
I would just dig down an inch or so, just enough to hold the short roots. Do not pile up any soil over the lower stems or it could cause root rot.
Water it in and keep an eye on it so it doesn't blow away before it gets established. You could fashion a couple of small hoops out of covered wire and anchor down the leaves in a couple of places. Be sure to remove those when the plant is established.
I found this agave at my moms in a pot. the stalk is almost growing bark and has roots coming off the bottom. What is going on with this agave?
This is normal. You will want to plant up to that first segment of leaves, as soon as possible. This article will help you with the care of the plant:
We do not know the name if it but the stem is very thick and there are other small flowers coming from the sides
It looks like a type of agave, possibly spineless, but I couldn't pinpoint the exact cultivar. Here are some ideas:
