Sorry, battery acid stains are permanent. The acid will eat away the cloth.
Copper+Nitric Acid - Copper Nitrate
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.
Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
No. Copper oxide has no acid-base properties.
boric acid
No.
if you eat it.

Because it has acid and it might kill you.
corrosion of copper, from battery acid vapors, most likely.
A battery acid is a variety of acid used as an electrolyte in a battery - usually sulphuric acid.
Copper+Nitric Acid - Copper Nitrate
yes, in fact they are used for a type of Voltaic battery.
Lemon juice is an acid. The metal in the paper clip reacts with the acid to produce an electric current. It's the same process as the electricity produced in a battery.

Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
