Thank you again for your help. Please advice how can I change social icon for custom? I need only two, but different from those in your theme - VK and Telegram. Looking forward to hear from you soon.

Add this CSS into wp-admin >> appearance >> customization >> additional CSS

.fa-facebook:before {
    content: "\f189" !important;
}
.fa-twitter:before {
    content: "\f2c6" !important;
}

Once you do this you can use Facebook as VK 

and Twitter as TElegram

Just update links going to wp-admin >> appearance >> customize >> Social links 

And kindly take a moment to rate our theme we will be very thankful to you thanks
