There are some things that do this, but I would first check your calcium hardness level.
Water is hungry for calcium and will try to get it anywhere it can. You need to feed its appetite.
While I agree with the notion that some pools need calcium, I prefer to keep my pools between 150-250ppm. This level comes from an index used specifically for pools. Anything lower or higher than this range comes from an index used for public water systems that was "grandfathered" in and used for pools because no other index was available.
Many pool guys will say keep your calcium at the higher end, about 400ppm. Keep your at 150-250ppm, get a good Taylor Reagent DPD test kit, learn the "swirl" technique, and you'll be fine.

You drain the water then plaster the walls from inside
Not usually. Has it beendrained and left dry for more than 2 - 3 days? B T W do not use the word "your" as in "your pool plaster... Your pool is 10 years.... Please use "My" pool.... and "Our" pool is 10 yrs..... When you refer to "your" you are talking about me and my pool. What do you know about my pool? Supposing I do not have a pool.
Depending on what the plaster surface damage is to the pool, it really is pretty easy to repair the plaster on your pool. You just need a chisel, or a small angle grinder if you are really handy, a hammer, a trowel, some water and a sponge. they sell pool patch kits for all the pool surfaces. look for pool plaster patch kits and you will find an easy to use solution.
It makes very little difference

No
Yes,you just need to patch the plaster first.
My experience is that the stains will go away by themselves, through the effects of the chlorination of the water. Does not matter if the pool is a salt pool or fresh water pool. If the pool has a plaster finish, brushing the stains with a wire pool brush will speed up the process.
First you have to determine if is in fact a painted pool. If it is a plaster pool then usually there is no paint unless it was painted because of age and damaged plaster. You most likely do not want to paint a plaster pool - have it acid washed to clean plaster. Not sure how to determine what type paint. You would have to have the paint chips anaylized to determine if it is a chlorinated base paint or epoxy paint. Ken
No, salt does not damage the plaster. Improper water balance will.
It might stain the plaster. When you have an algae bloom, get on it right away, don't wait. See the link below for more info.
Yes you can (re-plaster) There should be a company in your area that does the plaster for pools when they are built and also re-plaster as they get older. Your Pool supplier should be able to suggest who may be the most reliable. yes,
