Normal body flora is generally helpful to the organism. In fact having normal body flora occupies space and resources that could otherwise be utilized by pathogens. However, some normal body flora can be harmful if the microbe enters an area of the body that it would not normally be found and can cause infection. These bacteria are known as opportunistic pathogens.
A for instance would be your normal complement of Escherichia coil. Outside their small intestine environment the usually beneficial symbiont could initiate a fatal infection.

Normal microbiota
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.
The normal flora of the urinary bladder is typically sparse, as urine is normally sterile. However, some studies suggest that low levels of certain bacteria, such as lactobacilli and coagulase-negative staphylococci, may be present in the bladder. The presence of these bacteria is generally considered inconsequential unless there is an underlying medical condition.

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.

The fetus is surrounded by amniotic fluid of its mother. It acquires the normal flora of its mother. After birth, the newborn begins to acquire its own "normal flora". Humans have normal flora on their skin and in every body throughout life; it is not completely washed away although it can be changed, reduced, or disrupted by medications or changes in Ph or by actions humans take during hygiene or sexual activities. Then micro-oganisms of the normal flora become pathogens that can cause infection.

Everyone has "normal flora". Normal flora exists in the body, on the skin, and in every body opening. Your mouth's normal flora is likely different than the normal flora of your mother, father, siblings, cousins, and every unrelated person. That normal flora protects you from becoming ill or infected every time you come in contact with a micro-organism. People are also carriers of certain microorganisms. One person's body carries germs that may--or may not--have made that person ill in the past or present. If that person who is carrying a micro-organism may transfer that micro-organism to you, for examples, through shaking hands, kissing, or sexual intercourse. If the carrier's microorganisms overwhelm the second person's immune system, or their "normal flora", multiplication of the micro-organism can occur and cause an infection. Once multiplication and infection occurs, the micro-organism has become a pathogen.
Yes, usual flora, normal flora, and typical flora are all normal results.
superinfections.
Most women are surprised to learn they have a normal flora that contains yeast (men and women carry this flora). Women try so hard (too much) to keep the vagina "clean" often using douches one or more times a day. Then the Ph in the vagina changes and the normal yeast begins to multiply and the woman gets a "yeast infection". Although it seems to contradict what many women believe about physical health (especially for the vagina), trying to be "very clean" can actually set off the sequence of events that allows microorganisms to become pathogens and cause infection.
Microorganisms that colonize the host for hours to weeks but do not establish themselves permanently are called transient flora
candida albicans are a type of yeast (fungus) that grow as normal flora on the human body, but can cause varying symptoms if their growth is not in the normal range of human bodily flora
