Hello, i am a bit confuse about how to convert 6v dc to 200 v dc having a least power output of 25watts. is it possible?

Yes it is possible it is called a DC to DC converter.

If you want to buy one just Google DC to DC converter and pick one with the input and output you want.

If you want to build one search here for DC to DC converter or Google DC to DC Converter Schematics, Circuits, or Diagram, then you will need to tweak it to your needs.

Yes, its possible. You'll need your supply to be capable of at least 4-5 amps output.
