Nobody's gone and looked for Good Hope and Monmouth, so they haven't been surveyed. From what I've read on Coronel I doubt that either wreck would be in good condition - Good Hope's forward magazine went up and the Nurnberg pummeled the Monmouth prior to the latter sinking.
As for the Jutland wrecks, there isn't much left of Indefatigable as the wreck was heavily salvaged sometime in the 50's. Queen Mary's in two halves and upside down whilst the bow of the Invincible is upside down whilst the stern is upright, but heavily collapsed. I haven't seen any good images of Defence, but from various sources the bow and stern are gone whilst the middle part of the ship is in reasonably good condition. Warrior doesn't seem to have been found whilst the Black Prince appears to be in very poor condition.
Aboukir, Hogue and Cressy no longer exist as they've been demolished in order to improve the channel into Ostend.
For the Dardanelles wrecks, Majestic has been very heavily salvaged whilst Triumph and Irresistible are upside down and in reasonably good condition.
Formidable is also upside down and split in two just forward of the bridge.
Mike.
