Judgement Dragon is found in Light of Destruction booster packs as a secret rare and Turbo packs as an ultimate rare.
Judgment Dragon's effect does not target, so it can destroy Obelisk the Tormentor.
Yes, you can do that. Judgment Dragon activates its effect at Chain Link 1. Enemy Controller would be chained to this at Chain Link 2. Resolving backwards, you will take control of Judgment Dragon, then all other cards apart from Judgment Dragon will be destroyed.
Monsters do not have Priority, players do. Once successfully summoned, the turn player may activate Judgment Dragon's effect as chain link 1.
No, Stardust Dragon's negation effect is a spell speed 2 quick effect, which cannot be chained to a spell speed 3 card such as Solemn Judgment.
no, the same happens with Judgment dragon as he isn't a lightsworm
To Special Summon Judgment Dragon, you must have at least 4 different Lightsworn monsters in your Graveyard. Once this criteria is fullfilled, you can Special Summon it from your Hand onto the field.

Yes, it kills itself. Or else it would say "all other cards", like Judgment Dragon does.
Yes, it can. White Night Dragon can only negate Spells or Traps that target it. For one, Solemn Judgment does not 'target' anything, and for two, WND's negation effect is only active while it is face-up on the field after being successfully summoned. Solemn Judgment is preventing its summon.
'Best' can often be a matter of opinion, but at the moment, Dark Armed Dragon and Judgment Dragon are very popular and powerful, followed by Stardust Dragon, and Black Rose Dragon.Or 5-headed dragon with 5000 atk and def
Yes as long as you have 4 lightsworn monsters in your graveyard with different names. Remember that Judgment Dragon's summon does not require you to remove the monsters from the graveyard (unlike Chaos Sorcerer), so if the condition was correct for one Judgment Dragon, it's still correct for another.
