Egyptian hieroglyphs were first successfully deciphered with the help of the Rosetta Stone.
The Rosetta Stone (so name because it was dicovered in Rosetta - or Rashid) had the text of a decree of the Pharaoh Ptolemy the fifth inscribed in three forms, - hiroglyphs, Egyptian demotic and Ancient Greek.
By comparing the text in a known language with the hieroglyphs, Jean Francois Champollion was able to decipher the hieroglyphs on the Rosetta Stone (1822). His work served as the basis for the deciphering of other hieroglyphic inscriptions.

Yes
No, if you have to decipher something your doing that thing, so its a verb.
Jean-François Champollion used the Rosetta stone to decipher Egyptian hieroglyphics.
nobody made it, it just appear
There are 700 hieroglyphs
decipher code depends upon the algorithm you used to make them. there are no general methods.
There are only about 700 different symbols that were commonly used, but the total number of symbols used is unknown.

Decipher is a verb, so it does not become plural like a noun would. However, it does conjugate within the tenses. It is the same in all tenses except third person singular: I decipher You decipher **He/she deciphers We decipher You all decipher They decipher
