Armed Dragon LV 10 can only be summoned with the effect of Armed Dragon LV 7. Once you get that out and keep it out long enough for its effect to activate, tribute the LV 7 to call out LV10.
The effect of Call of the Haunted that destroys the monster it summons, is not something that 'activates'. Because it does not activate, there is nothing for Stardust Dragon to chain to.

No. It is an Ignition Effect, meaning you may only activate Snipe Hunter's effect during your turn.
Since DD Sprite can only be summoned during your own turn, its trigger will activate in the opponent's Standby Phase.
Monsters do not have Priority, players do. Once successfully summoned, the turn player may activate Judgment Dragon's effect as chain link 1.
Yes it can if you don't activate Stardust Dragon's effect. But you can choose to activate his effect to Tribute Stardust Dragon to destroy and negate EHAZs' effect.
Yes because it's effect says you can summon a normal dragon type monster from either players graveyard. So since tribute to the doom destroys the monster is effect activates.
If you know about the card Judgment Dragon, it's pretty much the same thing. You can activate its effect as many times as you want during your Main Phase 1 or 2 to blow up the field except itself.
I belive D.D. Warrior lady can activate her effect because her effect does not target.
Yes, Stardust Dragon can activate its negation Quick Effect in the Battle Phase, and even the Damage Step.
no, if you read it, it says that only you can.
Totem Dragon only has one effect that activates, the one that can special summon itself. If there are other monsters in the graveyard, that are non-Dragon types, then this effect cannot be activated.
Yes, it remains on the field and can attack as long as your opponent does not activate another effect.
No, it triggers in response to the declaration of the attack. If it is face down at this point, then it misses its chance to activate. When it is flipped face-up at the beginning of the Damage Step, it is too late to use its effect.
You can activate its destruction effect in your main phases, and can activate it as many times as there are valid targets for it, and you can keep paying the cost.
You can only activate and Special Summon "Red Eyes Darkness Metal Dragon" with this effect from your hand.
