Leaves are not smooth, but like crinkled, thirsty? Have tried repotting and not watering too often and misting. Still not growing or showing any signs that new leafs are going to be any different.
This could be lack of light or nutrition.
Make sure the plant is in a bright indirect light.

Can I trim the brown spot on the edge of the leaf? Sorry, I don't have any photos.
If the edges of your plant are turning brown dark, it can be due to build up of salts in the soil from conditioned water.
Try using distilled water to water your plant. You can also let tap water set on the counter for at least 48 hours before using.
You can trim the plant edges, but it may continue to turn brown until the salts are flushed from the plant.

It was doing great, then I moved it from direct sun to partial sun and now looks like it's diseased or something.
You actually have a Shamrock plant.

I bought this beautiful prayer plant a few weeks ago, and now it's dying. I made sure to keep the soil moist but not overly wet. At first I placed it near a window, but that seemed to be too much light, so I moved it into a room with less light. That seemed to escalate the death. I took it out of the original pot and separated the roots which were tightly clustered. Now I don't know what to do. YouTube videos advise an enclosed container to keep the moisture consistent, but I am not certain how I can do that with it in its current state. Please help.
The roots can dry out and die quickly if left out of the soil.
Your plant does not look good, and it may be a case of tossing it out and starting over.
You can propagate a leaf if you have any healthy leaves remaining.

It has 2 shoots with flowers blooming. The plant is otherwise healthy but not growing. Do the flowers drain growth? Should I cut them off?
Yes, the plant may slow growth while it is blooming.
You can fertilize your plant every couple of weeks with an all purpose fertilizer from May thru September.
This will help the plant support the flowers.

I have a crystal sugar like substance on the back of my prayer plant leaves? It falls off when wiped. Is this a fungus?
It seems this is common, and nothing to be concerned about, unless you are also seeing webbing. If there is any webbing, you could have a pest. Here is a link to articles pertaining to the plant: https://www.gardeningknowhow.com/houseplants/prayer-plant/
How exactly do I trim off the brown leaves on my prayer plant?
If the leaf is completely brown, it can either be removed simply by tugging gently, or you can cut it off at the base with sharp, clean scissors. If a leaf has crispy brown edges but still has some green, it is best to leave it on to help feed the plant, but if you need to for cosmetic reasons you can cut the leaf off at the base.
