It will activate no matter where it was sent from. If it had to be from the field, it would say so - like Sangan does.
Yes, Dandylion will trigger even if sent to the graveyard while face-down.
No. A card cannot be activated, if it is unable to resolve. Cards like Statue of the Wicked and Ojamagic, do not have a resolvable effect that can occur from activating them on the field. All their effects are triggers, which activate under other circumstances. Because nothing would resolve, they can't even be activated on the field. Ojamagic's effect only triggers after it leaves the field, so there'd still be no resolvable effect from trying to activate it on the field.
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.
Yes, it remains on the field and can attack as long as your opponent does not activate another effect.
Ocean Dragon Lord - Neo-Daedalus comboing with Dimentional Fissure let me say tho the Ocean dragon's effect is a pain to even attempt to activate but if you can activate it and you have DF already activated then your golden! (more or less) XD (as far as i no theres no such card and if there is either konami will make it a pain to use or its ban the card)
Yes, Dandylion will trigger even if sent to the graveyard while face-down.
No. The material monsters are no longer considered 'on the field' and none of their effects are active.Because they are not considered to be on the field, effects that specifically trigger when they go from field to graveyard will not activate either. For example if a Sangan is an XYZ material, it will not trigger its monster search effect when it goes to the graveyard.However if the monster does not say it has to come from the field, such as Dandylion, then these effects will trigger when they go to the graveyard.
No. The effect of Mask states that monsters cannot be tributed. Since stardust requires itself be tributed to activate the effect, you cant activate the effect.

In general, a monster's effect can only be used while it is face-up on the field. If it can activate in a different zone, such as hand (Gorz, Emissary of Darkness) graveyard (Necro Gardna) or while banished (Stardust Dragon) then it will say so on the card. This is why a card such as Cyber Dragon cannot freely summon itself from the graveyard every time the condition is correct - it summons from hand. Evil HERO Infernal Gainer has no such text, therefore the cost of banishing it to activate its effect, can only be performed while it is face-up on the field.

Almost. It's text clearly states that it "negate(s) the effect of all spell cards on the field". So as long as it's a spell card active on the field, it is no good. Some cards, however, activate when they are sent to the graveyard, but those are rare. but if u use the effect of destiny hero diamond dude then silent sworsman cant negate it
If you mean her effect that special summons a Fortune Lady, this only activates when she is removed from the field 'by an effect'. Offering her as tribute for any kind of cost, will not let her activate.
Yes, they can. You can also play another field spell to remove the one that is currently in effect.
Unless specifically stated otherwise (Royal Oppression, etc), you can only activate the effects of a card you have control of. If 'your' Winged Rhynos is on the opponent's side of the field, then in game terms, it is 'his' monster. He's the only one that can activate the effect.
