Our theme use font awesome 4.7 for icons, you can find and use icons from here https://fontawesome.com/v4.7.0/icons/ and If you need to integrate your custom icons then you need to create a child theme, need to load your custom icon css and use css class in BP: Services widget.
Hope this helps!
Have a great day ahead!
