I need some help on how to trim my trees.this first one is a Dominick tree whats a good way to Trim this tree for fruit production its 3-5 feet tall

 
This second one is a Chicago Hardy, its about 1-2 feet tall how should I trim or train it for good fruit production?
 
Last one is a Dwarf Red Delicious Apple Tree I already cut off a bunch of small Branches for better air circulation. Its also like leaning to one side can that be fixed or should I build a prop of some sort to hold it up? 
 
The pictures are all side ways for some reason even though i know I took them vertically

1st one is still young but i have alot of success cutting them way back so i would cut the roge brank at bottom off. Then cut the rest down to lower branch. If you dont you going to have a tree really tall and skinny
2nd. can leave it go. maybe cut the tall one back to all the same length
3rd start to shape the tree. Think of it with leaves. Decide how tall you want it.
My opinion may differ from others. ;-)

 
like this? cut at the red lines?

if i cut all the way down to the ground for fig tree 1 will it sprout from the ground and give me more of a bush?

You dont need to go to ground. And actually could leave the one branch by base of tree. And cut where ted lines are. Then next spring do more trimming

Okay thanks I'm gonna do that :)

For the apple tree, I would drive a sturdy stake in the ground a couple feet from the trunk, then make a loop around the tree and tie the end off to the stake, pulling the tree to straighten it up.  You can do it gradually, not all at once if it needs to move a lot.

I would leave the first two as they are until they break bud, come out of dormancy and grow at least five leaves on each limb. Then pinch the tips of all the limbs to force it to branch out. Run a search on pinching.
The third ,large tree.
Start at the very top of each limb and cut two thirds off.
It will also force the tree to branch out when it breaks. Remove all crossing and inward growing branches also and just like Richie said ,visualize how you want it to look before you start choping. There are some very cool videos on YouTube.
Best of luck.

i ended up cutting the two tall thicK branches down for the first one

Thanks will the tree sprout from the trunk or they only grow from buds?

I learned a lot from this fig pruning video:
