Many lighter cars earn 5 star crash tests these days, manufacturers create crumple zones and add air bags to help you survive a crash, use the compare feature to put the models side by side in the consumer reports website, or even KBB will do that as well.
The models you list above are not all alike, another aspect of your choice will come down to preference, then consider fuel mileage versus power, compact versus midsize, when you put it all together the decision will be easier.
A Jeep would very likely be heavier
Yes, it is definitely a heavier engine.
The manufacturer of the 1995 Honda Accord recommends 10W-30 weight motor oil. A heavier motor oil can be used in extreme climates.
It depends on the Honda. For example, a Dodge Charger is bigger than a Honda Accord. However, it is also smaller than the Honda Pilot (suv). It is true that the Dodge Charger has a lot more horsepower than any Honda. Hope that helps. :)
