My pepper plant produces blossoms which fall off ,as expected, to reveal the new fruit. But the fruit turns yellow and falls off after only several days.
This can be due to excess heat.

Add some Epsom Salt to the plant soil.
This article will explain.

leave it to grow even though its already changed colour? Do the peppers continue to grow in size after they start turning red? Or could it be they are just small bell peppers?
What you are seeing is mostly normal, however, adding fertilizers high in potassium and phosphorous, and making sure not to add any more nitrogen can increase the size drastically. Generally, peppers that remain small will be more bitter, but still edible by all means
Just the stalks are left behind, but the plants still set fruit.
There are a number of different pests that could be munching on your pepper plants' leaves. It might be worth examining one of your plants with a magnifying glass during the day or taking a flashlight outside at night.
Here's an article that will help you identify the pests and get rid of them:

On the bottom side of bell peppers some have 3 lumps and some have 4 lumps. Does this indicate whether they are male or female or just a wive's tale ?
All bell peppers have both male and female parts. The central portion of the flower with a "ball" on it is the female portion, whereas the yellow pollen bearing anthers that surround the female portion are male organs.

My green bell plant has been in my garden for about 2 weeks now. Planted from a Nursery, has started getting Brown spots on the leaves, and holes. Please see Picture
This doesn't appear to be anything problematic. It appears, mostly, as wind damage.
I would take care not to overwater, at this time. This will increase the likelihood of infection. Make sure that the soil is dry between watering when possible.

Year after year we seldom do better than one or two deformed red bell peppers. However tomato, squash and onions do quite well. I switched to drip irrigation this season with a timer option. Garden gets good sun exposure, about 8 hours daily. Native soil is heavy clay but I've brought in bag after bag of garden soil. I apply lawn mower mulched maple tree leaves in the fall and cover the garden with some occasional chicken manure in the Fall. There may be some unintentional lawn weed n feed that finds its way, but not much That's about the extent of fertilizing help!!! I lover red bell peppers but can't grow them
It could be the chicken manure. Uncomposted chicken manure can be a bit harsh with nitrogen, which can prevent uptake of phosphorus and potassium. This will halt fruiting, or make it fruit very poorly. Another thing could be proximity to tomatoes. They will compete at the root level, chemically, preventing one or the other from fruiting properly.
My bell pepper plant has black right at the beginning of the stems on the plant. Last week a small stem/leaf broke off and now it looks like this. :( what is causing it and can I fix it? Also, anyone know what’s eating some of the leaves?
The coloration is something that almost all peppers do. It will be no cause for concern. I don't think that the tattering is much to be worried about, either, unless it is spreading rapidly.
