Given the high heat and lack of rain this season, it has been a hard year for new plant installations, and even our established landscape plants are pretty stressed.
Camellias like consistent and even moisture but will resent wet soil. You are doing well.
Most of the browning looks like stress from leaf scorch.
You can pinch off the one in the second photo that is mostly brown and has a circular pattern to it and put it in the trash.
Overall though, the plant looks o.k. and has plenty of leaves to support itself.
Our area is right on the edge of winter hardiness for camellias and they can be difficult to keep alive, healthy and happy.
The ideal placement is in a sheltered, protected microclimate like close to the southside of a home. Mulch (no deeper than 3 inches and kept pulled back from the trunk/stems) is recommended during the growing season You can add more in late fall but remove excess in the spring.
Since these plants prefer an acidic soil, you could have a soil test done: https://extension.umd.edu/resource/soil-testing-and-soil-testing-labs/ and if needed, feed them in the spring with a fertilizer for acid loving plants.
Wrapping them in burlap for the winter isn't a bad idea.
