Westchester airport is smaller and closer if you're flying in there or by small plane.
Newark is little over an hour. LGA and JFK would take you roughly 90 minutes to get there. Please expect a lot of delays during the day. They have blocked a couple of lanes leading to LGA due to construction. So please plan accordingly.
All airports could have very different commute timings based on the day, the hour of commute
Westchester airport 30 mins with out traffic, Newark is approximately 1 HR, 15-20 mins, both depend on the traffic
Google maps will get you miles and time based on current traffic. (From/to or current location to destination). Put Google maps app on your phone...you'll love it.
Newark airport it like an 1hr 15 minutes
Newark Airport probably 50 minutes, The New York Airports could be double that depending upon the time of day
Depends on which airport
