Hi Tomson,
I hope you are well today and thank you for your questions.
And there are some issues I can’t defeat. First of all I would like to customize slider in such a way that single slides don’t redirect into posts, but they take user into other section of website.
You can achieve this using child theme solution shared in the following topic.

Second issue is setting width of main section with heading Main Page. I would like to create website without grey margins. Content of website should take 100% of width and height. What Should I override?
You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.
Admin Area -> Appearance -> Customize -> Additional CSS
.container.main-content-area {
width: 100%;
}
Best Regards,
Movin
