“I assumed I’d gone down in her estimation now both my sons have dropped out. But I miss her company. We’d have been out there having a fag on the pavement once upon a time." Having a fag is slang and does mean smoking. Dropped out is also an expression which means leaving schooling. “Gone down" means declined.

Ventilation is merely having the proper access to oxygen for breathing purposes. Breathing is what sustains humans. Inhaling and exhaling air from our lungs.

" My cold is finally gone." Is a perfectly useable sentence. "My pain has gone"; Doesn't work since you're using a possessive pronoun with a present perfect tense. It should either be "It's gone" (The pain) or "My pain is gone"

"Diverted" means to change direction. The sentence is merely stating that it was more economical for the Western States to change routes and go along the Erie Canal.
