AgBr
AgBr precipitates and in light decomposes to bromine and silver metal.
AgBr+No2+o2
Silver bromide (not bromine) is one of the silver compounds used to create the "emulsion" that records the latent image before it is developed. It is the most widely used of the silver salts, which are compounds that react to light and create the latent image. Bromine (not silver bromine) is released when the developer acts on the silver halides if the emulsion is silver bromide based. I'm not sure if that is the result of a chemical reaction between the silver halide and film developer, or if the bromine atoms are already present due to the reaction between light and the silver halide. I only mention this because bromine is in your question although I think you meant bromide. The bromine can be utilized to reduce image contrast in high contrast scenes, but I believe it is not widely known how to develop film in this manner, hence you probably weren't asking for the usefulness of bromine.

2AgNO3 + MgBr2 ----> 2AgBr + Mg(NO3 ) 2
AgBr precipitates and in light decomposes to bromine and silver metal.
There is NO reaction between Cu and Ag.
There's NO reaction between AgNO3 and HNO3
AgBr+No2+o2
2Ag + ZnSO4 = Ag2SO4 + Zn

This reaction follows the equation Mg + 2 AgNO3 -> Mg(NO3)2 + 2 Ag. Products are on the right side of a chemical equation; therefore, the products in this reaction are magnesium nitrate and elemental silver.
This equation is:AgNO3 + KBr = AgBr(s) + KNO3Silver bromide is a white precipitate.
No Reaction
One balanced equation for the reaction between elemental copper and silver nitrate is Cu + AgNO3 -> CuNO3 + Ag.
The reaction is:Ag+ + (NO3)- + K + I- = AgI(s) + (NO3)- + K
The reaction between sodium chloride (NaCl) and silver nitrate (AgNO3) results in the formation of silver chloride (AgCl) which is insoluble. Thus, the net ionic equation isAg^+(aq) + Cl^-(aq) ==> AgCl(s)
