The first and the last pictures look like [Tobacco Mosaic Virus][6]. 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][5].

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][3] (1)
* [Tobacco Mosaic Virus on a tomato][1] (2)
* [Tobacco Mosaic Virus on a pepper][2]

I might recommend planting resistant varieties next year. I don't know of any particular treatment for this year.

Varieties resistant to Tobacco Mosaic Virus that 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)

Reason for suspecting tomato yellow leaf curl virus:
