Common practice is to charge everybody mentioned in the FIR. Most common charges are 498A,406,323,34IPC. Generally speaking, no one will consider any proof from your side at this stage. No one will question about the authenticity of the proofs submitted from other side. If you have a ‘say’ in the PS where the FIR got registered, you may get a few names dropped from the FIR after showing some relevant proofs.
