1 - Ships move around and don't remain in one static location

2 - ....that "green liquid" is Wildfire, a fictional substance allegedly made using alchemy and outright magic. Yes, gasoline fumes are what burns, not the liquid - wildfire it's the actual liquid that burns. Even direct sunlight can make wildfire explode.

3 - ....Theon was limping, and/or adrenaline, plus he was riding a horse for most of that.

4 - Again magic. White Walkers aren't exactly the kind to leave footprints.
