Destroying a monster does not flip it. But if a monster is flipped face-up when attacked, and considered destroyed by battle, then the flip effect will still activate.
No, the Gladiator Beast monster must successfully declare an attack and survive until the end of the Battle Phase when you would send the back to deck for another monster. Here's some additional rules to Gladiator Beasts for the offical site, YuGiOh-Card.com: The effect of the "Gladiator Beast" monsters that says, "At the end of the Battle Phase, if this card attacked or was attacked, you can return it to the Deck…", returning the "Gladiator Beast" monster to the Deck is a cost to activate the effect.If you do not have any "Gladiator Beast" monsters remaining in your Deck that you can Special Summon, you cannot activate the effect of the "Gladiator Beast" monster that attacked or was attacked. For example, if "Gladiator Beast Murmillo" attacks or is attacked and the only "Gladiator Beast" monster remaining in your Deck is another copy of "Gladiator Beast Murmillo", you could not activate the effect of "Gladiator Beast Murmillo" at the end of the Battle Phase.If a "Gladiator Beast" monster attacks or is attacked during the Battle Phase and the "Gladiator Beast" monster becomes flipped face-down by an effect during the Battle Phase, even if the "Gladiator Beast" monster is flipped face-up before the end of the Battle Phase its effect to Special Summon another "Gladiator Beast" monster cannot be activated."Divine Wrath" can be chained to the effect that returns the "Gladiator Beast" to the Deck. The effect will be negated, but the "Gladiator Beast" monster will not be destroyed because it is in the Deck.If 2 or more "Gladiator Beast" monsters attack or are attacked during the Battle Phase, at the end of the Battle Phase the effect of each "Gladiator Beast" monster can be activated. The effects will activate and resolve separately. They are not combined onto the same Chain.You can return face-down "Gladiator Beast" monsters to your Deck to Special Summon a "Gladiator Beast" Fusion Monster, but you must show your opponent the "Gladiator Beast" monsters to verify that they are correct.If you take control of your opponent's "Gladiator Beast" monster and attack with it during the Battle Phase, you can return it to your opponent's Deck to Special Summon a "Gladiator Beast" monster from your Deck if you have a "Gladiator Beast" monster in your Deck that you can Special Summon..You can use a "Gladiator Beast" Fusion Monster when Special Summoning another "Gladiator Beast" Fusion Monster.

No, flip effect activate when the card is flipped, which will be by Flip Summon, or being attacked, or flipped by an effect. Simply being destroyed while face down, will not 'flip' the monster.
Yes they do, as they activate their effect when they are destroyed and sent to the graveyard.
Flip effects will activate if flipped manually by Flip Summon, or when attacked. Also must include "FLIP" in all caps for its effect to activate, or say 'when this card is turned face-up'. For example if a monster such as Guardian Sphinx is flipped face up by an attack or an effect (spell, trap or monster), the effect does not activate, because only a Flip Summon triggers it, not a generic flip. When a card effect destroys a face-down monster, the monster is destroyed and flip effect isn't activated because the monster never flips. Mystic Swordsman Lvl. 4 destroys the monster it attacks without flipping it, so a Flip Effect monster attacked by it will not get its flip effect. To summarize, if a FLIP effect monster is attacked while face down, then it will activate. But if it's destroyed by a card effect while face down then it won't activate. Some card effects let you flip monsters face up and let the flip effect activate, like book of taiyou. But others, like ceasefire don't let it activate. If it says 'when this card is flipped face up' then you have to do that manually on your own turn.
No, Gladiator Beasts must survive battle, for them to activate any of their 'if this card attacked or was attacked' effects.
Yes. When Grapha is discarded by an effect, its trigger will activate. You can chain Gladiator Beast War Chariot to negate this activation.
Yes, it's a Triggered effect, negation cards such as Gladiator Beast War Chariot can be chained to it.
Destroying a monster does not flip it. But if a monster is flipped face-up when attacked, and considered destroyed by battle, then the flip effect will still activate.

No, flip effect activate when the card is flipped, which will be by Flip Summon, or being attacked, or flipped by an effect. Simply being destroyed while face down, will not 'flip' the monster.
It must survive a battle that reached Damage Calculation. If the Gladiator Beast monster is destroyed by battle, or survived it but is flipped face down or removed from the field before the end of the battle phase, then it cannot trigger its effect. Also, if the attack never reaches Damage Calculation (such as an attacker attacking the Gladiator Beast being flipped face-down by Book of Moon) then it can't trigger in that situation either.
If you mean, is it destroyed when it 'levels up', then no. It is simply 'sent to the graveyard', it is not a 'destroy' effect and cards that look for or trigger from something being destroyed, will not activate.
Yes they do, as they activate their effect when they are destroyed and sent to the graveyard.
As an Optional Trigger, the destruction must be the last thing to happen. If it is destroyed, but something else 'happens' (a summon, a resolution, etc) before it gets chance to activate, then it has 'missed the timing' and is not allowed to activate at all.
No. The only time it flips in being destroyed is when it is attacked by a monster. The flip effect will only work if the monster says "FLIP" in all caps and does not say if it is destroyed in battle that its Effect will activate.
No part of Zubaba Knight negates effects but since it destroys the monster at the start of the Damage Step it might mean that some monster effects would be unable to activate. Monsters which trigger when destroyed by battle will not activate because they were destroyed by an effect. Many monsters with effects that happen during or after Damage Calculation will never activate because the damage step will end as soon as it starts.
