Each of the items that you have listed involves Special By-Laws, and requires a Special Resolution at your General Meeting where no more than 25% of those Proprietors in attendance (personally or by proxy) vote against the Motion.
I’m a non-smoker, but I’d urge you not to become too caught up in the recent publicity about non-smoking By-Laws, particularly as I seriously doubt that an Owners Corporation can create a Special By-Law that prevents residents from smoking inside their Lots.
In any event, remember that even if passed, none of the items mentioned in your post has any legal standing unless each is properly Registered on the Title of your Plan.
Best of luck!
