Hello, Dear Cemre.

Please open in code editor file style.css located in /wp-content/themes/beautyagency/style.css and add to the following code in string 1847 display: none; rule: http://nimb.ws/8gq06E

.header_style1 .header__top .top-bar-right {
    padding-top: 10px;
    padding-bottom: 10px;
    float: right;
    text-align: right;
    display: none;
}

This step will hide unnecessary icons from top right side of the header.
