No because the card is already active. Cursed Seal of the Forbidden Spell can only negate the activation of a spell card, not the trigger of the effect.
Once every turn
No, it is an Ignition Effect and can only be used in your turn.
i stopped playin yugioh like 7 months ago,but dark hole is forbidden,so,just dont use it
Stardust Dragon has a triggered effect that special summons it from the graveyard on the turn that it negated an opponent's effect. Forbidden Graveyard will negate this trigger, Stardust Dragon will not be summoned.
geminis must be summoned a second time to get the effect while effect monsters only need one summon
Forbidden Chalice will negate Marshamallon's 'cannot be destroyed by battle' effect. Because Forbidden Chalice changes the ATK of a monster, it can be used in the Damage Step, after Marshmallon is flipped by an attack. If you did this, you will not take the 1000 damage from Marshmallon either - his damage dealing effect activates after Damage Calculation, but will be negated.

yes
Exodia the Forbidden One's effect is - when you have five different pieces of The Forbidden One in your hand, you may declare an automatic victory.

No. Once a monster is targeted by something, then subsequently protecting it from targeting will do nothing. The targeting part already happened, even though Forbidden Dress will resolve before Sazank's effect. Secondly, Sazank does not destroy the target, so Forbidden Dress' other protective property will not apply. A destroy is a special kind of send, but it doesn't work the other way around - an effect that simply sends to the graveyard is not a destroy.
No. It is an Ignition Effect, meaning you may only activate Snipe Hunter's effect during your turn.
