The easiest way to do this is to create separate views and bring them together in a dashboard. You can modify each view the desired fonts as you like. Dashboards are typically the fastest/easiest way to customize views.
There is one other potential method using @Multi-axis_Crosstab - see this discussion - Re: Using multiple measures and shapes on a single worksheet for an example. But for such a straight forward viz as the one you have above, I would just use a dashboard with multiple views embedded.
I hope this helps,
