STDs do not cause brown sperm.
No.
No, but there are conditions which man make that happen. Hematospermia, for example, can make your semen reddish brown. It happens when there is a little blood in your semen. It's perfectly natural and shouldn't cause worry. If it's really pretty dark brown, then you should head to your doctor. You might have an STD.
Well, it's your own semen and you have STD. It won't makes you get worse since you produce it yourself...
The rifampin in the semen will not cause any problems, but their semen may not be safe to ingest. Rifampin is an antibiotic given for many reasons, including STD's. If the rifampin is being given for an STD then it would not be safe to ingest the semen, not because it has the rifampin in it, but because it may still have infectious particles in it.
There is a medication called rifampin that can cause semen to be orange in color, but it also makes your tears organge, your saliva orange, and your urine orange too. If only your semen is orange, then it is likely you have an STD and need to get it checked out by your doctor.
Unless it has an STD, then no it is harmless.
