You can still activate them, but Royal Decree negates all other traps except itself, so they will be negated. You can however activate such a card like Seven Tools of The Bandit to negate the activation of Royal Decree itself and destroy it, because Royal Decree does not apply the negation effect until it resolves.
Yes. Royal Decree only negates the resolutions, it does not negate nor prevent activations.
As a Spell Speed 2 card, you cannot chain Royal Decree to a Counter Trap. However if Royal Decree is already active, any Counter Traps that try to resolve, will be negated.
Jinzo, Royal Decree and Trap Stun negate the effects, Trap Jammer, Solemn Judgment, Seven Tools of the Bandit negate both activation and effect.
'Negation' can have two different contexts. You can negate a card's activation (meaning the resolution never happens) or just negate the effect (meaning it resolves but does nothing). Solemn Judgment can negate activations, Royal Decree negates resolutions, and also switches off the effects of continuous traps.If you negate the activation or the effect of Normal Traps and Counter Traps, then that means you don't get their effect. If the negation effect destroys them, they will go to the graveyard on destruction, otherwise they will go to the graveyard when the chain finishes resolving.If you negate the activation of a continuous Trap card, then it is unable to remain on the field, and it will go to the graveyard.If you negate the effect of a continuous Trap card, then it will be able to stay on the field, however will do nothing until the negation effect ends. So if it was an active Royal Decree that was negating it, its effects will become active again if Royal Decree leaves the field. This goes for both chaining a negation effect to the activation of the continuous trap, or activating one later on, while the continuous trap is face-up and active.
Trap Stun, Royal Decree.
Yes. Royal Decree only negates the resolutions, it does not negate nor prevent activations.
As a Spell Speed 2 card, you cannot chain Royal Decree to a Counter Trap. However if Royal Decree is already active, any Counter Traps that try to resolve, will be negated.
Yes. When Grapha is discarded by an effect, its trigger will activate. You can chain Gladiator Beast War Chariot to negate this activation.
Jinzo, Royal Decree and Trap Stun negate the effects, Trap Jammer, Solemn Judgment, Seven Tools of the Bandit negate both activation and effect.
Seven Tools of the Bandit is a counter trap, and therefore spell speed 3. If your Royal Decree is set, then you may not activate it in chain because it is only spell speed 2. If Royal Decree is already active though, it will negate Seven Tools when it tries to resolve.
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.

This depends on the specific monster and its abilities. If a monster's summon is negated and the monster destroyed, it is likely that its effect was never able to be activated in the first place. In this case, its effect would never have applied
If royal decree is not in the chain, yes. However, if your opponent activates, for example, mirror force, then you chain trap jammer, then they use a trap jammer, you would not be able to activate royal decree because it's got a spell speed of 2. Only counter traps have a spell speed of 3 and to counter a card, you need to play a card that is the same or a higher spell speed. So in the example, mirror force would not be negated because their jammer would negate yours.
The first one that resolves will negate the effect of the other one when it resolves to the field. The other one will be face-up on the field doing nothing until the first one leaves the field.
No, no traps can be activated while Jinzo is face-up on the field. There's no exception for Counter Traps.
No, because you're unable to remove any cards from play. Since you can't pay the effect's cost, you can't activate it.
