Is it necessary to thin figs out on young trees, have a 2 yr old grafted I assume negronne and Peters honey, with 50 plus figs on each, will they go to full fruition, I say grafted because the main trunk on these 2 yr Olds is thicker than a 3 yr old tree

It is necessary, and especially if they aren't pushing out leaves. I would take half off or continue taking more off until they start growing vegetatively. There's a nice balance there that I think is acceptable. If the tree isn't getting bigger you won't have nearly as many figs the next season because this year was too much to handle for them. 

There are tons of leaves and the roots were massive like a 5 yr Olds tree, I have two yr old trees and the roots are not big at all, these thing are circling and dense, in the 3 gallon pot they came in it was more similar to a super tight birds nest

Sounds like the trees with 50 figs a piece are much older than 2 years old. In which case I would keep the figs on. Again, make sure the tree is growing. And be sure to fertilize if you haven't, and up pot to a larger pot next year or root prune and keep it in the same sized pot.

Pictures would definitely help!

I have no idea how to post pics it keeps saying file exceeds whatever

When I up pot I like to prune or at list cut circling roots so the roots do not strangle tree

Hi.
Somebody had mentioned before to open the picture in Paint.  In the Paint program you can reduce the size of your picture.  I've been doing 50 percent and the pictures still look fine.

HTH

cheryl is correct, resize in paint

I just email pictures on my phone to myself and it asks me what size to reduce them to , I choose the highest number under 1,000 and after I sent email I save picture and delite original to eliminate confusion
