False fir under 326 ipc

My uncle got into fight with the neighbors and both were injured. Both filled FIRs under 324 IPC and other sections. Neighbor falsely said in his FIR that I and my brother also attacked him. After 15 days, they converted 324 to 326 and my uncle got into custody and got bail after a few days. I and my brother applied for anticipatory bail in Sessions court but it was rejected, then we applied for bail in high court, in that my brother got anticipatory bail but mine was rejected. After this, we went to Chief of Police and explained our situation, he changed the Investigation Officer, new IO took fresh evidences and it seems that it will be in our favor. 1) Now, what will be the procedure to remove my name/acquittal of mine? Can the police do that by themselves or they will have to go to Sessions court? Or high court(since my AB was rejected by high court)? 2) How many days does it normally take to remove the name if Police Report is in favor of me? 2) Will I be able to file false fir case under Section 211 if my name is removed? 3) What other legal remedies do I have at my disposal if FIR is proved to be false? (It will be partly false since my uncle was involved in fight)
