Now I am confused with my Cherry Tomato plants.

So, I thought they would be over watered because it is raining a LOT atm in Mx, every single day, and even though I put them by the wall under a ledge, they still get rain, so I thought "I will not water them"... then the leaves were looking flimsy and started curling... I thought "My bad, they are not watered enough" and I started watering them, leaves on top stopped wilting and curling, and now look healthy, I have a ton of fruit(green, still) but now leaves(2 leaves in one of the 4 plants) is yellowing, so I have no clue now, if they are overwatered, underwatered or wth is going on.

You have some leaf miners. But the yellow could be a deficiency of something.

A pic of the entire plants would help narrow it down a bit.

If they are in pots continuous watering will wash through any nutrients. They need to be fed regularly with a tomato food.
