The information you are reading is probably from a MSDS sheet for spray on chrome,
For activator you can create one Liter using Stannous chloride 10 Grams, 20 ml of Hydrochloric Acid and then use enough Di water to make 1L solution.
For the Silvering formula, 3 grams of Silver Nitrate in a 500ml of Di water, then 3 grams of sodium hydroxide, this will generate a reaction that will generate Silver Hydroxide, then you dissolve this with ammonium hydroxide, I think it’s about 10 ml, but slowly add about 5 ml until the dissolve the Silver Hydroxide until the liquid is clear, then add enough Di water to make 1L of solution.
For reducer, 5 grams of Glucose and 1 ml of formalin(about 30% strength Formaldehyde) per 1L of water.
That is a very basic set up, you would need to try it first then do adjustments as you see fit.
