my ews rank is 12809 is there any chance to get any nit / iiit /gfti through jossa counseling in any branch
Yes you can get a good branch but chances of getting higher branch like CSE or IT is very low but you can get this branch in lower colleges like some of low rank GFTIs. To get CSE or IT in NIT or IIIT your EWS rank must be below 9k. But you can get ECE, ME or EE in any NIT or top GFTIs. If your home quota is in any state of north side India then there is chance you could get IT or CSE in your state NIT because NIT in norths have high closing rank for home quota students.
