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.
It cannot negate the activation of a trap card. It is basically the opposite of Magic Jammer. Mystical Space Typhoon can destroy face down spells and traps, continuous spells and traps, and field and equip spell cards.
The new ATK (minus the 500 for trap jammer) would be used in damage calculation.
The chain resolves in reverse order. Negate Attack will resolve first, and the attack will be negated. Trap Stun will resolve second, applying its trap negating effect. Then Mirror Force's resolution will be negated due to Trap Stun.

No. "Trap Jammer" can only be used on Trap cards; "Fusion Sword Murasame Blade" is a Spell card. Plus, "Trap Jammer" can only be activated during the Battle Phase. If you meant Magic Jammer, then yes. Fusion Sword Murasame Blade's protection effect is only applied after FSMB resolves initially, becoming active. So you can negate the activation and destroy it before that, or you can even chain Mystical Space Typhon, destroying it before it resolves, again before the protection effect becomes active.

As long as you are in the Battle Phase, then yes, you could use Trap Jammer against Crush Card Virus.
Trap Stun, Royal Decree.
No, note the difference between 'negate' and 'destroy'. When 'Magic Cylinder' activates, it doesn't matter what happens to the 'Magic Cylinder' card, it will not stop the activated effect from resolving. Chaining 'Dust Tornado' to it will do nothing. What you need is a card that will negate the effect too, such as 'Trap Jammer' or 'Solemn Judgment'.
No, she can only negate Spell, Trap or Monster effects that Target. Dark Hole does not target anything.
"Trap Reactor・Y FI" chains to the activation of a Trap card, destroys it, but does not negate it. The Trap's effect will still resolve even though it is gone from the field. If the Trap is Continuous, when the chain resolves and the Trap is destroyed, the effect of the Continuous Trap will disappear because it is no longer on the field. (This rule only applies to Continuous Spell and Trap cards.) This card cannot chain to Counter Trap cards.
Bottomless Trap Hole does not target, so Tyrant Dragon is unable to negate it.
The chain resolves in reverse order. Negate Attack will resolve first, and the attack will be negated. Trap Stun will resolve second, applying its trap negating effect. Then Mirror Force's resolution will be negated due to Trap Stun.
