The pickup in the foreground is a 46-47 Ford. The pickup in the background is a 51-52 Ford. The coupe looks like about a 46 Ford.
What DonMan said. the pickup in foreground could be 42-47, as that design was introduced for the 42 model year, cut short by WWII. I have a friend with a 45 Ford pickup (military) with same front clip. The coupe could be as late as '48.
