Here is the solution to change the title font - Change font and size of the title
To change the font of other elemetns in your widget, please add this code to the Custom CSS field on the Appearance tab of your widget’s settings:
.eapp-file-embed-grid-layout-component {
font-family: Calibri!important;
}
As for the changing the color, do you want this white background to be changed on hover?
