#1 appears to be a Peltier Rainbo. Not very easy to find in the boulder size.
The damage on the slag makes it worth zero cents. It's just cool that someone loved it so much.
Sticking with modern foreign on #2, probably Asian.
Sticking with Jabo on #4.
That leaves #3 .... You got one solid view of one of its seams, but I still don't know what it is. Hmmmm ... I'm going with Peltier Rainbo on that one. I'm not 100% on it, but between the long seams, and the 3 or more ribbons, and the light seediness of the base glass which I think I saw in one of the photos ... Peltier Rainbo is my vote.
