Becks, curling of the top leaves of toms is common, often caused by over-watering and/or too much fertiliser.
The peppers. It's hard to tell even after magnifying the photo, but the white spots don't look like scorching on the leaves. Are the spots powdery and on the leaf surface? Or are the spots sunken?
Do the toms - and the peppers for that matter - live indoors or outdoors? The toms have a leaf mould problem. It's a very good housekeeping idea to take off the lower branches to maintain at least a foot of clear air/space between the lowest branch and the soil.
The second last photo is a good example. The two lowest branches shouldn't be there. The second lowest branch - pointing towards the camera - is the diseased one and you can also see early signs of disease on the lowest one pointing away from the camera. Fungal spores will drop from the leaves to the soil. Maintaining at least a foot between the lowest branch and the soil helps against the spores splashing back up onto the leaves when watering.
In the meantime, all you can do is remove the affected foliage - including the branches that shouldn't even have been there! - and look for as much air circulation as possible.
