No, they're not balanced.
And they really need more detail to be sure how they work and when they're available. But 11 or more copies of stackable DR 1/- would be rather powerful, and an extra +11 or so to attack rolls or AC would be too. Now, granted, the Fighter gives up an average of 1 hp/level and 2 sp/level (before considering the likely lower Intelligence of barbarians) compared to a Barbarian, but through WF, GWF, WS, GWS, MWM, RWM, and Supreme Weapon Mastery or whatever it was called (PHB2), a Fighter can already have nearly as much accuracy and damage output as a raging Barbarian ALL the time, without any temporary stuff like Rage needed. And the Fighter's many remaining feats beyond that would give him much more versatility in combat than the Barbarian.
That stuff considered (and excluding for a moment the Fighter's capacity to take Martial Study and Martial Stance from the Tome of Battle as bonus feats for added power/tricks in each encounter), Fighters are only slightly worse than Barbarians overall. They don't need a handful of multiple-selection pseudo-Epic feats to bring them in line (your Attack! feat, frex, is basically Epic Prowess without the Epic-level requirement).
Now, say, if Attack! required Greater Weapon Focus and maybe 4 or 5 points of BAB per copy of Attack! acquired, thus limiting it slightly in how often it could be taken, it might be alright. If Defense! specified what kind of AC bonus it grants (I assume a dodge bonus?), required Dodge, Mobility, Combat Expertise, 3 or 4 points of BAB per copy of Defense! taken, and say 8+ levels of Fighter, it might be okay. If Stand Your Ground! required Toughness and maybe 2+ levels of Fighter, and could only be taken once per 2 points of BAB possessed, then it might be fine. If Battle-Hardened required Die Hard, Great Fortitude, Toughness, Endurance, 4 or 5 points of BAB per copy of Battle-Hardened taken, and say 6+ levels of Fighter, it might be okay. You might even change these BAB requirements to that many levels of Fighter needed per copy of the feat.
