I agree that this range of abilities is probably quite rare, even among more "well-rounded" athletes. And, as others have said, squat max should be lower than deadlift by about 20-25% for most people who train both. As a fairly thin person who started lifting, it took me about about three months of serious training to hit 2x body weight in the deadlift, but, even though I think I'm better suited to running and endurance sports, I find the 5:30 mile is harder to reach than some of the lifting goals. Also, I'm not an expert on vertical jumps, but 2/3 height seems excessive. Just about no one who isn't already a runner could go out and run a marathon without training--at least without a lot of pain and serious risk of injury.
The standards the OP suggests aren't bad as fitness ideals, and that could be one entirely legitimate measure of athleticism. However, what most people think of as "athletic" involves successful competition. Personally, I think both are legitimate definitions, but, in practice, I do see them as somewhat mutually exclusive, or at least mutually counterproductive, because being an effective competitor requires specialization and not spreading oneself too thin.
As for the question of terminology, I suppose it's like being "rich." Again, most people would think of someone with a net worth of $5 million as rich, but someone with a net worth of $50 million would also be rich, but on a whole other level--an "ultra high net worth" individual. For me, I'd use the term "athletic" more broadly, even, frankly, to include people who have high levels of fitness in a few areas, not all, and perhaps below the high standards of the OP. I think it's useful to view physical ability and condition on a continuum of "fit," "athletic," and "elite." If I had to make an arbitrary definition of "elite," I'd say someone who holds their own (or could hold their own) on the national level at some form of sport. A good example might be qualifying for the Olympic trials. A good local 5k runner would be athletic. I'm sure I'm being generous by a lot of your standards, but I'd even call an adult male with a sub-20 minute 5k time athletic, because that is something probably less than 1% of the population will ever accomplish.
