We had a good rain storm and it bent my 4 o'clocks to the ground. I'm wondering if I should cut them back or would the heat kill them? I propped them for now.
If they are just bent, not broken they just stand back up on their own in a week or so. The article below advises not propping them up as it might cause more damage.

I have south and east facing big windows . Will they be okay next spring.
If any of the plants in her yard have seeds, get some of them because they grow very easily from seed.
Your two small plants may be OK over winter, but you can also let them rest by saving the tuber. Here is how:

I live in NY where winters are too cold for 4 o'clock tubers to survive. But I grew 4 o'clocks in pots this past summer. So if I let the plants die out, let the soil in the pots dry and keep these filled pots w the tubers indoors over the winter, will the plants regenerate when I put the pots outdoors in spring?
I believe they would. And you could just keep the pots in a frost free area like the garage and let them go dormant. Give them a little water once a month. Or you can dig the tubers and save them overwinter. Here is an article that tells how.

Also, if you collect the round, black seeds and save them, those will grow quickly next spring. You probably will see some seedlings come up in the ground around the pots as well. They are notorious self seeders.
What to use to keep insects from eating the leaves
Spraying your plants with a Neem oil solution will stop insects from eating or laying eggs on the leaves of your plants. You can also try an insecticidal soap. You didn't say what kind of insects are eating your plants, but Japanese beetles are known for feasting on 4 o'clocks.

They have been really healthy, however our region was hit with catastrophic wildfires. Due to the smoke, several of my plants aren’t fairing well. Could it be the same thing as my other plants??
It could be due to smoke, which can clog the plant's tiny pores used to absorb carbon dioxide. Smoke can also destroy chlorophyll, thereby reducing photosynthesis. Try rinsing the leaves with water, and applying fertilizer to give it a boost.
I would also examine the leaves for insect pests (though smoke can deter them).

I would make a boquet out of the 4'ok tower will stay bloomed after cutting?
Once a flower is cut, it will start to die very quickly. There are a few things that you can try to keep it for longer. Here is an article that will help:

I'm collecting the seeds as they fall off of last seasons plants, to replant them in a different area of the yard, but some of the seeds already collected, have a white coating of something on them. Are they no longer viable?
Unfortunately, your photo did not come through. I am unable to see the problem in question.
Generally, fuzziness on seeds can be attributed to fungal issues. In most cases, it renders seeds non-viable.
