Hello,
I saw the screenshots you attached.
There are no specific image sizes for each of the items you mentioned in the screenshot.
In our demo we have used the images of the following sizes:
1) Shop Single: 700×800
2) And the slider is not only one image it uses the images and background color combinations that you can check by editing the slide from Dashboard >> Slider revolution.
3) The brand image used is 180×100 px.
4) The Blog image is 1024×720 px.
5) Page title background image is 1900×634 px.
6) To remove the shipping and delivery tab you need to Go to Theme Settings >> Product Page >> Tabs.

Clear everything in the area mentioned in the screenshot above.
You can edit the HTML Block to edit the content from Dashboard >> HTML Blocks.
Best Regards.
