i want to ask you question about how can i deprotonate or use
deprotonated cysteine because I have protein with “cys” in active site,
and I want to use deprotonated
“cys”. when i run “pdb2gmx “  no option appearing of choosing Cys
deprotonated state possibility


That's correct. You can edit the rtp file to add support for CYS-, e.g. 
name it CYM and then name the residue in your pdb file CYS instead of 
CYS as well.
