A. monster reborn can special summon all type of monster from the grave
this card can only be stopped by a trap while is activate or a quick spell
monster reborn can bring back any monster from the grave unless the monster u want from the grave says it "can not be special summoned from the graveyard" or says "this card can not be special summoned"
A monster's special summon text only applies while it is in your hand. If a monster says it can 'only be' special summoned by a certain method, then assuming you do summon it properly, and it is then destroyed, then you are allowed to use Monster Reborn and do not have to pay any additional costs. If the above monster was simply discarded from hand by something else, then it can not be special summoned by Monster Reborn. If it says 'cannot be special summoned except by..' then it can't be brought back with Monster Reborn even if it was properly special summoned first.
Vampire Genesis 'cannot be special summoned' except by following the instructions on the card. If a monster says it can 'only' be special summoned a certain way, this is for the initial summon only. If you summon it properly, and it is destroyed, then you can revive it from the graveyard with Monster Reborn. However the 'except by' monsters can't be special summoned by any other means than the text on their card. Even if they are properly special summoned first, you still can't use Monster Reborn on them.
Yes, you can.You can special summon Synchro Monsters from the Graveyard, but they need to be properly Synchro Summoned first...Just like a Fusion monster. You see, if you properly synchro Summoned a monster and your opponent used "Lightning Vortex", you can simply use a "Monster Reborn" or any other card to recover it; since it was properly summoned. Although, if it is sent directly from your Extra Deck to the Graveyard by a card effect, you can say "bye-bye" to that card for the rest of the duel.
If you mean monsters, then "Monster Reborn" ...(then again, they forbid that card a while ago, but oddly enough you can still get it)
no, special summons are NOT the same as normal summons. special summons require a special card or effect to happen, cards such as monster reborn or return from the different dimension. normal summons are just when you directly play a monster from your hand without any other additional card effects
No, Elemental Hero Dark Gaia cannot be special summoned, except by the effect of 'Dark Fusion'. You cannot use any other special summon methods (like Monster Reborn), or even other fusion summon methods (Polymerization, Re-Fusion, Future Fusion).
yes, as long you did a normal summon any monster that turn.
Yes, a Special Summon of any kind does not count towards your limit of one Normal Summon or Set per turn. You can Special Summon as many times a s you want per turn.
Chaos Sorcerer must be initially summoned from hand. You cannot use his own special summon effect from any other location, like the graveyard. However, if he is properly special summoned by this method, and then destroyed, you are allowed to special summon him from the graveyard using cards like Monster Reborn. Monsters who say "can only be special summoned by..." all work like this, but ones who say "cannot be special summoned except by.." can't use any other method but their own. Lastly, if he's in the graveyard but was not properly summoned (like, his summon was negated, or he was simply discarded there) you can't use Monster Reborn on him.
Tribute is only needed for the monster's Normal Summon or Set (or Special Summon in special cases). Flip Summoning does not require any tribute at all, regardless of what monster it is.
If it was properly summoned by Synchro Summon, then yes, it can be brought back, assuming it has no other restrictions. That means if it got to the graveyard in any other way (ie, tried to Synchro Summon, but it was negated, or it was 'only' special summoned by Vayu, or was sent there by Gale Dogra), then it can't be reborn.
