I think BLeafe has the trolley yard location correct. That's the back of the big bank building, and the houses are probably those on the west side of River Street. The east side must have had no houses.
As for "picture #3", that's a bigger mystery. There's a house close to the street, so it's likely an older part of Hackensack, in the immediate vicinity of the downtown. There's no hint of hill or incline. There's open space or a park on the right. And the trolley track is making a bend to the left of 90 degrees, or close to 90 degrees. And the street it is turning onto is only about 2 blocks long. That's the tough part, I've gone back to the map 10 times to look for that configuration. I'm having difficulty with that one, but if I had to guess I'd say it's somewhere around Mercer Street.
Picture #4 is also a big mystery, the trolley through the woods with one building in the distance. Must be what is now Summit Ave, looking north. Somewhere south of the Susquehanna Line.
