The first and the last pictures look like Tobacco Mosaic Virus. The mottling looks like it matches. The others, I'm not sure, but they could just need more of the right nutrients, and they may have a fungal infection. It may be too early to tell for sure what's wrong with those. I don't know if they also have a virus.
Alternately, it could be Tomato Yellow Leaf Curl virus.
Here are some links to pictures that led me to believe Tobacco Mosaic Virus was likely the case for the first and last pictures:
- Tobacco Mosaic Virus on a tomato (1)
- Tobacco Mosaic Virus on a tomato (2)
- Tobacco Mosaic Virus on a pepper
I might recommend planting resistant varieties next year. I don't know of any particular treatment for this year.
I could be wrong about Tobacco Mosaic Virus, but that's my guess, at this time.
Resistant varieties I recommend looking into include these:
- Yolo Wonder pepper
- Chef's Choice Orange F1 tomato (also resists anthracnose; AAS award)
- Chef's Choice Pink F1 tomato (also resists anthracnose; AAS award)
