My bell pepper plants have grown lush foliage all season, but they are producing very few blossoms, and hence, little fruit. What could be the problem? We live in Zone 5/6 (central Ohio, urban area), and it's been very hot this summer, but we're getting plenty of rain.
It sounds like you have too much nitrogen in the soil. This creates lots of leaves and few blossoms. Add phosphorus to the soil to help re-balance it. Bone meal is a good source of phosphorus.
Bell pepper plants healthy looking but fruit has brown spot. Can you help me?
This is blossom end rot. This article will help:

We planted red and orange bell peppers this year for the first time. They are getting large and not yet turning red and orange. If we pick them when they're still green, will they still ripen if we set them in the window where they get sun?
Once a pepper is picked, it will stop ripening, so picking them green will not work.
My bell peppers all have black spots on the fruits. The peppers seem to have thin walls and poor fruit shape as well. The spots become holes in the peppers and the seeds are few in the damaged fruits. I have side dressed the plants with coffee grounds recently and am starting to get stronger peppers, but I would like to make sure I take care of this permanantly. I just saw some birds leave my pepper patch which might explain what happens to the exposed seeds of my bell peppers.
It sounds like your issues are starting with sunscald. This is a common issue with peppers. It creates a thin brittle patch on the fruit, which is easily damaged and then start to rot (which is the black spots). Sunscald is caused by too much direct sunlight on the fruit. Try providing some shade for your peppers with either a shade made of an opaque material (like a sheet) or with an umbrella. This should help stave off the sunscald and help keep the other issues at bay.
My bell peppers are getting rotten before they ripe. How can I prevent this?
This is known as blossom end rot. Here is additional information: https://www.gardeningknowhow.com/edible/vegetables/pepper/pepper-blossom-end-rot.htm
My green bell peppers, that are almost to the size to be picked, have developed brown areas on the top surface that cover about 25% of the area. The plant is in a large pot on the east side of the house and receives sun until around 3:00 PM. Is this too much sun, or is it something else?
It sounds like sunscald and it is from too much sun on the fruit. Try providing a little more shade for the plants to prevent this.
My bell peppers are covered with a clear sticky substance, also tiny white (almost clear) spots. The leaves seem to be affected also, but not as much as the actual peppers. I'm in southwest Arizona. I have destroyed the plants this year, but wonder if there is something I could do to prevent this again.
It sounds like the plant had scale. This article should help with keeping them away in the future: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm
