    Yes if your roof is leaking, that is the likely source of it.

    generally moisture   for mold to grow it needs some moisture source

    now a LEAKING roof can be  OBSERVED ...... the humidity in a room  can be from other sources  as well as a leaky roof  are their moisture stains on the ceasing  that is also observable and a thought association

    Your humidity is too high. Get a humidistat and dehumidifier then keep the level below 50%.

    Yes but not likely.  More likely that you never open the room window to get in some fresh air. Mold hates fresh air as fresh air is dry and mold likes it moist and warm like UP YOUR NOSE.  Breathe on a mirror and see that there is moisture droplets coming out of you. Every breath you exhale is moist so it is enough for mold to grow.

    . Leaking roof leaves a water stain on the ceiling, sometimes it looks like a bathrub ring...in brown or black.

    Yes, or to high humidity levels in the house, a lack of insulation or improperly insulated in that area.  Or, in the case of a roof where there is an attic on top. Something stored in the attics that will not allow the roof and insulation to breath properly.

    Yes, but it can also be a condensation issue if your ventilation is inadequate.  Do you dry laundry indoors (not in a tumble drier), shower with the bathroom door open, or regularly use a lot of saucepans without a lid?
