What does it mean by shared stereotypes? I know that stereotype is like an image that has a certain meaning. How would that relate to smokers? I don't know but would that be like commericals that are related to smokers or like others that smoke for the same reason?

Advertisement suggest that if you use the product the "cool" person in the ad uses, you will be equally as cool. That would be sharing an image of coolness or stereotype.
What would be another example of Shared stereotypes for smokers?
Another example would be from the point of view of people's (or a person's) opinion. Such as - all smokers are unhealthy and not athletic. Or another would be - smokers aren't concerned about their health because they continue to smoke. Or another would be - smokers are weak people who don't have the will power to quit.
What does it mean by Mind Guarding? How would that affect people that smoke?
From what I found, mind guarding is a characteristic of groupthink. Those in a group protect themselves and the group by avoiding any dissenting ideas. For smokers, mind guarding may the unwillingness to seriously consider the cigarette's potential health dangers to themselves and others.
Would an example be like second hand smoke?
Yes.
Direct pressure to conform placed on any member who questions the group, couched in terms of "disloyalty". How would direct pressure affect smokers? Would it be like lying to someone that that they don't smoke or pressure from peers is the reason for why their smoking?
Yes. Those are good examples.
