no it must be cleaned first- you can use some bleach or any mold cleaner
let it dry well to see how deep it is set in- then add a primer paint- if it bleeds through again you may need to re do it- there are mold drywall cleaners- if this is in a bathroom use t.s.p so the paint will stick if need be-it must be cleaned right the first time

No, you should never paint over mold. If it's substantial, you should hire a mold remediation company to remove it, if it's limited, use a 50:50 water to bleach mix to kill the mold, allow the area to dry completely, then clean the area, prime any bare wood and paint with either an oil or latex paint.
Yes you can. You can paint on almost anything. The only thing with painting on moldy wood is that mold will soften the wood making the paint chip and crack easier.
You should wash out and disinfect the mold. Then paint it over with a couple layers for the best results. After all of that you should buy and put some primer over the older paint. That will make the paint last much longer and shinier. After all this you will have nicely painted areas of you house.
A wood Primer is required to coat the wood before the paint is applied. The Primer seals the wood and is better suited to being painted as the wood alone will soak up the paint causing it to dry too quickly and peel.
theres 2 ways you can lightly sand over it. it give the paint some texture to hold on too. are you can kilt over it and that will allow you to paint over it
What do you mean? Yes, paint on wood trim is typically latex these days. Some older homes may still have alkyd (oil), though. To find out for sure, put a little nail polish remover on a cotton swab and rub it on the paint in an inconspicuous location. It it gets soft and starts to come off, it's latex. Either way, sand it lightly and recoat with the same type of paint and you're good. If you're asking about bare wood, DON'T USE LATEX! The water will swell the grain of the wood. Use an oil primer that is made to take latex topcoats.
Most paint dries faster on wood.
If you paint over the "weathered" paint, it will chip and cause the stain to come off. Also, the stain needs a clean sanded surface in order for the wood to absorb it. Otherwise, there is no reason to use stain.
