Hi,
Typography can be controlled over 8THeme Options -> Typography, if you didn’t find the setings there,
You meant you want to change the font for those mentioned areas? If so, use this Custom CSS in Theme Options -> Styings -> Custom CSS,
.product_title.entry-title, select, .price, .woocommerce-Price-amount, .tabs .tab-title { font-family: Arial; }
Change that to some other font of your requirement.
Let us know,
Thanks,
laranz.
