yes all you got to do is use lemon juice.
Hydrogen peroxide are mixed with dye and or lightener/bleach to make your hair lighter.
Yes go swimming and let your hair dry in the sunlight it doesn't work for all brunette though It will make it lighter.
go to a professional...or slowly dye your hair lighter and lighter.

Bleach
You'll probably get a ashy brown depending on how light that grey color is. If you want to go lighter you could use a toner instead of bleaching your hair or try dying your hair 1 shade lighter each time you dye it
Not sure but during the summer(or when its warm out) you can squeeze lemon juice into your hair and it'll make your hair lighter colored
Yes. It makes the color lighter though. The more you put in, the lighter the color. Hair dye is pretty much made up with conditioner
This is not really a shampoo, but hydrogen perozxide can make your hair lighter for a period of time. This chemical is like a dye for your hair, though some of the side affects include premature grey hair and hair loss.
yes, but whatever colour you dye it will be lighter than on un-bleached hair
I have dark hair but know hair pretty well. For example, my friend had blond hair and died it to brown. When you dye hair, the old color goes down to the end of your hair, so it will be lighter on the bottom. If you wash your hair the color will get lighter. If you dye your hair darker when it's light, your hair will be different shades and the dye usually doesn't stay in long. Also dying your hair that aggressively isn't healthy for your hair.
Yes, but you can get a funky color if you do it wrong.
