The first two are beyond my paygrade and would disable until you get PS up and running. More knowledgeable people will probably comment.
With the GPU message update your drivers from the manufacturers site.
The first 2 are because you mistakenly copied plugins from a previous version of Photoshop.
You need to go remove all the plugins you mistakenly copied from a previous version. Remember that the plugins folder is now just for third party plugins...
The last message means you have an older or unsupported video card - if you have display/drawing problems, you should update the drivers or turn off the GPU in preferences.
