I bought red pepper plants from the store. There are green peppers growing. My question is, will they turn red? Or, do red peppers start out red?
Yes, they will eventually turn red. All pepper varieties start out green and will turn as they age. This article should help: https://www.gardeningknowhow.com/edible/vegetables/pepper/how-to-grow-red-peppers.htm
This year my husband and I are attempting to grow red peppers. Last year we had more cucumbers and tomatoes than we knew what to do with. As of yet, we have not seen any actual 'fruit'. The plants are fairly large and seem healthy, but nothing. All of our other vegetables (tomatoes, cucumbers, string beans) already have stuff growing, especially the string beans, which we've been eating now for about a week. We struggled with a very rainy June and not a lot of sun. Could that be the problem? Is there hope that we'll get peppers this year?
It sounds like you have too much nitrogen in the soil. This creates lots of leaves and few blossoms, which are needed for fruiting to occur. Add phosphorus to the soil to help re-balance it. Bone meal is a good source of phosphorus.
Should red pepper plants be staked or do they vine on the ground?

How do I know when to pick them because for the second year in a row, the peppers get big but never turn red or yellow? Should I take a risk and leave them or pick them in fear of them rotting on the plant?
Why are my red bell pepper flowers dying? I have nice flowers for about two or three days and then the stem and flower are gone from the bush. I water every two days and I'm always on top of them caring for them as usual.
It sounds like a pollination issue. The high heat and humidity in many parts of the country has been affecting pollination. Or it could be plant pollinators are having trouble getting to the plants. Peppers and tomatoes are identical in how they pollinate so you can use the information in this article to hand pollinate the flowers: https://www.gardeningknowhow.com/edible/vegetables/tomato/pollinate-tomatoes.htm
Our red peppers look great except the bottoms are turning a yellowish brown and look diseased. I have not cut into one to see what is inside, but am afraid to eat them. The plant is in a container and gets watered daily.
This is blossom end rot. The peppers are safe to eat, just cut out the bad spots. This article will help you fix it:
