I'm a bit fuzzy on these years, but best guess would be a 1963 Galaxie, might be the mid year facelift or a 1964.
1. The Mustang appears to be a '65, but the first 3 years are difficult to tell apart - and this one has a few mods.
2. Eye-Q is spot-on with the 412 ID.
3. The Ford is a '63 Galaxie, but it has had most of its trim removed, so it's not possible to say if it started life as a Galaxie 500 or just a plain Galaxie. I'd be inclined to guess that it wasn't a 500.
