Mealybugs

I think I have Mealybugs in my Tomatoes i was told to spray then with Vinegar and water others told me dish washing liquid.
please let me know if this is correct here are some pictures of the disease tomato leaves

I do not see mealy bugs in your pictures.
When there are few they usually hide where the leaves join the stem, or where branches are attached. When the population is so great that the damage in pictures 3 and 5 are present I would expect to see blobs of white quite obviously in the pictures, in many places on the plant.

Insecticidal soap (follow label directions), or liquid dish soap @ 1 tablespoon per gallon can kill them, and many other insects.

Looks more like a viral fungus disease / mould, rather than aphids or other sap sucking insect problems.
I would take a rough guess and say you have had a wide variation in temp, maybe even less air flow caused by humid weather then perhaps cold nights when plants were still young and tender. My dad used to say, "never handle tomato plants after smoking a cigarette" as it causes or leads to viral infections, the Tomato and Tobacco, Potato are all related, but there are several types of viral infections that strike Tomatoes and some, once established bring other diseases and aphids that attack weak plants, when I say weak plants, this applies to other plants too, not only Tomato's.

I would instantly remove the dead and dying plants, the ones worth saving should have the diseased foliage removed and BURN this as it carries the spores that as you work removing the foliage, the dusty spores will puff like powder and be carried on to other plants either from your hands, clothes, air and please also sterilise your cutting tools or next plant you go to with these items in hand.
The fruits should NOT be un-edible however, they will be small, un flavoursome and not nice fruits you want from any Tomato plants.
Next year you need to make sure there is a better place to grow the plants where they get better air flow, DONT water the foliage, only the roots, don't allow the plants to get too dry between watering and IF you see even one leaf turning yellow, remove it right there and then.
Feed with Tomato feeds as the flowers begin to appear BUT never over feed, start with HALF dosage that is given on the bottle and after a week or so you can increase the dosage BUT not over dose.
Tomatoes have a short growing and production season and when you think they are seeds, then little plants, produce leaf, grow taller, flower then fruit all in the space of months, then they do need a lot of water, feed, attention to health and when they are growing to their best ability, they sure reward us, what we sometimes have to cope with is out of our control like cool evenings early on, lack of moisture at the right times and of-course, pests and diseases,

Hope this helps you out, maybe you have LOST this years plants but make sure you DONT plant any Tomatoes, or related family off in that area for several years, in between this, you can start to prepare the soil over the next few years for growing that area again with Tomatoes. you can meantime grow other plants there till the soil is well rested from the fungal or other diseases that has affected the Tomato's.

Truth is Horse, everyone who grows Tomato's will have been met with these problems so please don't take this to heart, start again, maybe buy a few ready established plants for this year to give you some confidence after this shock, BUT please don't give up growing stuff because of one failure.
Best Regards.

Thanks that was helpful, just so you know I already ate some of the early tomatoes and they appeared great
