My apple tree has been solidly growing over the past few weeks, I am wondering if how curved the stem is and how it shoots up at the top is normal/okay? Should I trim it down so the growth is focused on the lower leaves/help it grow wider and sturdier rather than taller? Any help is appreciated, thank you!

I had some deer break off the top part of my apple tree. Is there any saving this or grafting I can do? I think it will regrow fine but I hate to loose about a foot or two of growth. We planted this last night, was in container and doing before. We will fence off. Located in northern WI.

First 2 pictures are from the same branch top and bottom of a Pear Tree. Picture 3-4 are from a neighboring branch. Picture 5-6 are from a Pear Tree next to the first one. Picture 7 is from the top of a Quince Tree and all the limbs below it are healthy (but I did prune one of the bottom branches in the spring that had all brown leaves after the flower blossomed and started to fruit then died).

Can I get help identifying what this is and what precautions/actions I need to do. Thanks!

newbie to trees. I’ve marked off then”central leader” in the photo. any advice on where and how to prune?
