    It sounds like you may have a pest on the trees. There are several that can cause damage like this, but they are all treated in the same way, which is with a pesticide. I personally like neem oil as you will treat pests and fungus at the same time, plus it is organic and safe for consumption. Here is more information on it:

    If you have not fertilized in awhile, you may also want to fertilize the trees. This can help them to fight off the pests.

    A week of no water should not have that effect that quickly. But, it would not hurt to provide water.

    Has the tree been fertilized recently? If not, I would add some fertilizer to the soil (after it is well watered to avoid burning the roots). The stress of producing fruit with low nutrients may be too much for the tree and its leaves are yellowing because of that.

    As a precaution, I would recommend treating the tree for pests and fungus. I like to use neem oil for this because it does both and is organic. Here is more information. https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

    Yes, neem oil is great for this. This article has an outline of the spray schedule:

    I'm not sure if you mean limb or trunk. If it's the trunk, you're in trouble. Peach trees need a sturdy single trunk to support growth. You can try taking the tree down and allowing a shoot from the base to grow, but you'd probably be better off planting a new replacement.
    If it's a limb, trim it back to the break and let nature take its course.

    I have to say that I am stumped. I have not heard of this before. I would recommend taking a picture of it to your local extension service and have them take a look.

    If your tree has lots of flowers but no fruit, I'd suspect that either the blossoms were killed by a late cold snap or there weren't enough pollinating insects around.

    The ants would not have killed it, but would be an indicator of something else wrong. If the ants were on the outside of the tree, say in the canopy, the likely cause is aphids. Ants will gather where aphids are because they use the aphids like little cows and milk them for their sweet honeydew. The aphids would be the reason for the trees' decline. Aphids can be treated with a pesticide.

    If the ants were in the interior of the trunk, this would indicate that the heartwood is rotting (which made it soft enough for the ants to tunnel through. This does not bode well for the trees and you would need to have an arborist look at the trees and tell you if they are salvageable or if they must be cut down.
