it is totally manual we might need to change the characters their type their animations

I'm afraind I don't understand what you mean by this. Please use punctuation or create separate sentences describing everything in more detail, otherwise we will have a hard time guessing what exactly you mean.

there are also no call backs or animation events with SkeletonGraphics

This is not true, SkeletonGraphic provides the same callback and event APIs as SkeletonAnimation, you can access it normally via skeletonGraphic.AnimationState. What are you missing?

also facing anchoring issues

If you are facing anchoring issues, most likely your SkeletonGraphic's RectTransform bounds have not been setup to match the size of the skeleton. See the documentation here on how to set it up in one click:
spine-unity Runtime Documentation: Match RectTransform bounds for correct visibility
What is not yet supported is automatically resizing the skeleton alongside the parent's RectTransform, currently it will only move without scaling. We have an issue ticket for it here:

We can’t make Animator state machine out of skeletongraphics for unity ui like this image I shared here. Can anybody suggest solution to this?

Currently SkeletonGraphic only supports the same AnimationState based animation API as SkeletonAnimation. There is some rewriting of the main components (SkeletonAnimation, SkeletonMecanim, SkeletonGraphic, SkeletonRenderer) in progress which (if everything goes well) will allow to use SkeletonGraphic with the Mecanim API like SkeletonMecanim. We have moved this feature to the 4.1-beta spine-unity runtime however, as 4.0-beta is already very late in its beta phase and shall become stable 4.0 soon. You can find the issue ticket here:
https://github.com/EsotericSoftware/spine-runtimes/issues/1414

If you do not want to wait for this feature in 4.1-beta, you can use a Mecanim wrapper around SkeletonGraphic as demonstrated in the example scene Spine Examples/Other Examples/StateMachine SkeletonAnimation/Mecanim Logic SkeletonAnimation View.scene that comes with the spine-unity unitypackage. This script would need to be adjusted accordingly to target SkeletonGraphic instead of SkeletonAnimation, but this should be rather easy to do.

Glad you've figured it out, thanks for getting back to us.

Most likely you have adjusted the wrong bone or misunderstood what your programmer means by "get the anchor pointed shifted to the center of whole image". Bones and attachment images can be translated to any desired location, so there should be nothing preventing you from accomplishing your goal. Could you please show a screenshot of your setup in Spine?
