Flipping either Number 11: Big Eye, or the target of its effect face-down will not stop the effect from resolving as normal.
Once every turn
No, it is an Ignition Effect and can only be used in your turn.
geminis must be summoned a second time to get the effect while effect monsters only need one summon
The website then you can say everything a regular yugioh card has but you can change the picture, effect, name, any number of att and def, any attribute, any type and and creator. If you have the type of paper a regular yugioh card is then you would have the strongest deck ever.
Yes, it does.
Trap Hole is not being 'chained to' the summon. Summons cannot be chained to. What is happening is that Prime Material Dragon is being successfully summoned (ie, not negated) then Trap Hole is being used in response. Because of that, it is perfectly fine for Prime Material Dragon to chain his effect to Trap Hole.
No, the lifegain happens only once.

Fiendish chain stays targeted to the monster and negates its effect when you enter end phase

If Eradicator was chained to Grapha's eff targeting Ophion, then Eradicator will resolve first, tributing Ophion and destroying 1500 or less ATK monsters. Grapha's effect will then resolve. Since the intended target, Ophion, is not on the field anymore, Grapha's effect resolves with nothing happening.If Eradicator was chained to Gate's effect, then Eradictor will do its effect and since Grapha's effect will only activate after the card effect discarding it resolves, Grapha' effect will not activate. So after Eradictor and Gate resolve, Grapha will select a target, which can't be Ophion as it's no longer on the field and destroy it.

The Equip happens on resolution of an Ignition Effect. Book of Moon can be chained to that. The target monster will flip face-down and then the Equip effect will resolve without effect because it can't equip to a Set monster. Inzektor Hornet will not move from whatever zone it started in.

Red-Eyes Darkness Metal Dragon's effect is an Ignition Effect so cannot be chained to anything.
