Answer 1

Random branches turning brown throughout, usually, indicates a root rot issue. Be sure that the soil has some time to dry out between waterings, at least to 2 inches or so.

Cut, only, the affected branches, and treat with a fungicide. This along with letting the soil dry out adequately will address the issue. Here are some articles that will help:

Thanks. I guess we will try a fungicide and hope for the best. they look healthy other than that.
