Welcome to the ehealthforum and I am really glad to help you out.
I can understand your concern but you do not have to fear any of these medical diseases. Lichen planus and yeast infections are not related to sexually transmitted diseases. Lichen planus is thought to be due to an abnormal immune reaction provoked by a viral infection (such as hepatitis C) or a drug.
Treatment is mainly by topical and oral steroids like clobetasol proprionate and betamethasone proprionate ointments which are generally applied for 4 -6 week courses. Severe cases may need immunosuppressants and phototherapy.
Regarding the persistent yeast infection, it can be due to incomplete treatment , treatment resistance, co-existing dermatitis, diabetes and low immunity. You should get your blood sugar levels checked. The medicines that have been prescribed are correct and you should use them under your doctor's guidance.
Regarding herpes, it is a sexually transmitted disease. However to confirm whether you are having herpes or not, you should get investigated. Laboratory tests which should be conducted include: culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction (PCR) to test for presence of viral DNA and antibody test.
Non reactive HIV means negative and hence you should not worry about it.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
