SO what my question is that after the end of season 7 November 8th.!! I ended G5 alright so is it possible still being able to play ranked during pre season will I get demoted? will I loose my rewards or are my rewards locked in ? someone please explain this to me IF a rioter could explain it to me that would be great I would highly appreciate it.

Your rank is locked in at the end of the season, November 8th, and that will be your displayed rank and coordinate rank to what rewards you receive. During Preseason, you are still able to play ranked in hopes of increasing your MMR before the reset, which can give you a better MMR after your placements for the next season if you raise your rank a bit beforehand.
So, as long as they have no changed it as of recent, ranked games during preseason will not affect your "rewards" rank, but will affect your hidden MMR after placements for next season.
