There is still air inside of a house, which is pushing the roof upwards, so the forces are equal and the roof is not crushed.

Consider this situation: A baseball player dives head-first

Of the forces listed I think the force of him diving and sliding across the infield acted on the player.

I think so because the slowing down was a result of an action, and I don’t think that should count as An action when it is the result of an action. However, the act of diving head-first into second base and sliding across the infield are independent actions and will cause friction, which will act upon the player.
