Normal flora can be a barrier to entry in several ways. The living bacteria that lives in our bodies wants to stay living there. If another organisim comes along it is going to protect it's territory, so to speak. They have defensive mechanisims to prevent other bacterial intruders from gaining entry to the body.
Another term for normal flora is indigenous microbiota or resident flora.
The brain and spinal cord have no normal flora, as they are considered sterile environments in healthy individuals.
Cerebrospinal fluid (CSF) is typically a sterile fluid, meaning it should not contain any normal flora. The presence of bacteria in the CSF is abnormal and can indicate an infection, such as meningitis.
Flora exists in various parts of the human body, in both men and women. Vaginal flora, or microbiome, in normal levels has no disadvantage. It helps the vagina stay "normal", clean and healthy.
Normal flora are microorganisms that permanently reside in or on the body without causing harm, known as resident flora. Transient flora are temporarily present on the body and can be acquired through contact with the environment or other individuals. While resident flora play a role in maintaining health by competing with harmful bacteria, transient flora can potentially cause infections if they enter the body.

Yes, usual flora, normal flora, and typical flora are all normal results.

You said that in your answer too. As the flora is normal, there is no harm
Normal flora cannot cause a "disease". But if normal flora is disrupted it can become a pathogen and then cause infection. Some diseases, like diabetes, can disrupt normal flora and cause infection, especially yeast infections on the skin or in the vagina of women.

In general, your "normal" skin flora protect you from "rogue" flora which might do you harm.
yes
The brain and spinal cord have no normal flora, as they are considered sterile environments in healthy individuals.
Yes, normal microbial flora can become virulent or pathogenic if the conditions are right. On outside of body normal flora is harmless, if it was to be ingested it would take the opportunity to do as much damage as possible.
barriers to entry are a set of agreements that prohibits a company from entering a certain market.
