For ques. no. 2 – Currently one Condition is missing in the theme( We will update in the next update ) – for now please use this CSS to hide btn label

#must-read .entry-content a{
    display: none;
}

For ques. no. 3 – Add this CSS to make font color white

.gdbbx-widget-profile-login h3{
    color: #fff;
}

For ques. no. 4 – Add this CSS to make font size the same as others

#colophon .footer-widgets-area .widget > ul > li{
    font-size: 16px;
}
