A monster's ATK can never drop below 0. If an effect would bring a monster's ATK into the negatives, it instead becomes 0.
A monster is destroyed if the ATK of a monster is become 0 or lower if it was the effect of Slifer the Sky Dragon.
Alexandrite Dragon is strongest.
You cannot manually. Such an occurence could only result from a card effect.
There are two different "kinds" of Toon monsters that behave slightly differently. The newer Toon monsters state the following:While you control "Toon World" and your opponent controls no Toon Monsters, this card can attack your opponent directly.So as long as you control "Toon World", a Toon monster can attack your opponent directly even if they control monsters.However, the older Toon monsters and "Manga Ryu-Ran" state:This card can only be Special Summoned while you control "Toon World". ...When "Toon World" is destroyed, destroy this card. If your opponent doesn't control a Toon Monster, this card can attack your opponent directly. If your opponent controls a face-up Toon Monster, you must select it as an attack target.Unlike the newer Toon monsters, these monsters can attack directly even if "Toon World" is not on the field. This is because if "Toon World" is removed from the field other than by being destroyed (returned to your hand, returned to your deck, etc.), your Toon monsters will not be destroyed as well. And since there is no requirement for "Toon World" to be activate so they can direct attack, they can do just that.
Some monsters (like "Quilbolt Hedgehog") turn blue while in defensive mode in the 5D's anime to further contrast the visual appearances of attack and defense position monsters. Perhaps it was determined that it wasn't enough to show a monster crossing its arm, kneeling, etc.
You do.
Assuming the defending monster is also in attack position, both monsters will be destroyed.
no

Your monster is destroyed if the monster you attack is in attack position, and you lose life points.
You cannot manually. Such an occurence could only result from a card effect.
When a monster attacks a defense position monster with DEF equal to to the attacking monster's ATK, no damage is inflicted to either player's Life Points and no monsters are destroyed in battle. Some monsters have effects that activate before or after they battle, so you must take those into account as well.
No, not at all. You can attack their attack position monsters first if you want.
Yes. It will be destroyed by battle by anything that has an ATK of 1 or higher (A monster with 0 ATK cannot destroy another with 0 ATK even though they are equal and normally equal attacks mean mutual destruction.

No, however there is a monster with equal ATK and DEF - Five Headed Dragon. Five Headed Dragon is the more useful card as it can easily be summoned with dragons mirror and can only be destroyed by light attribute monsters, thus a quick application of DNA Transplant renders it indestructable.
