Fusion Monsters that are summoned without using Polymerization (and similar) cannot be summoned via Future Fusion, meaning you can't select them for Future Fusion in the first place. Other monsters that this applies to are Gladiator Beast Heraklinos, Armityle the Chaos Phantom, and the Neos fusions such as Elemental HERO Dark Neos.
No, "Versago the Destroyer" cannot be used as a Substitute-Fusion Material monster in the Fusion Summon of "Cyber Twin Dragon". "Cyber Twin Dragon" specifically states: A Fusion Summon of this card can only be conducted with the above Fusion Material Monsters. This card can be Special Summoned from the Extra Deck using "Cyber-Stein" or "Metamorphosis", but if it is Fusion Summoned, two "Cyber Dragon" cards must be used. The closest you can get to a Substitute-Fusion Material monster for "Cyber Twin Dragon" is if you have "Proto-Cyber Dragon" on the field. (It's card name is treated as "Cyber Dragon" while on the field.)
Cyberdark Dragon cannot be summoned except by Fusion Summon. Cyber Stein does not 'fusion summon' the fusion monsters is summons, it is only a special summon. It therefore cannot summon monsters like Dark Paladin, or Cyberdark Dragon.
No it can't. VWXYZ has the 'no fusion substitutes' text "the above cards". This means the cards you remove must have the same name as those are listed, thus a substitute cannot be used. If a card can change its name, then it can be used, Elemental HERO Prisma is one that can do it.
Goku
if you have the necessary cards (fusion materials) in your hand to fusion summon yes, since fusion monsters have their own deck area.
No. VWXYZ-Dragon Catapult Cannon can only be Fusion Summoned with its own described method.
It's not an episode, it's one of the many DBZ movies that exist outside of the cannon.
Rainbow Neos is a fusion of Elemental Hero Neos, and either Rainbow Dragon, or Rainbow Dark Dragon.
Yes, Rainbow Neos is the fusion
No, "Versago the Destroyer" cannot be used as a Substitute-Fusion Material monster in the Fusion Summon of "Cyber Twin Dragon". "Cyber Twin Dragon" specifically states: A Fusion Summon of this card can only be conducted with the above Fusion Material Monsters. This card can be Special Summoned from the Extra Deck using "Cyber-Stein" or "Metamorphosis", but if it is Fusion Summoned, two "Cyber Dragon" cards must be used.

go on the dragon history and win tournaments
Any five Dragon-type monsters can be used to fusion summon this monster in conjunction with the Spell card "Polymerization" or other fusion Spell cards (like "Future Fusion" and "Dragon's Mirror").
It does not count as fusion material if it is equipped to cyber dragon. In the event that it is equipped to cyber dragon during the fusion for cyber end dragon armored cybern would be treated as a normal equip spell and would be sent to the graveyard.
he used his fusion cannon to stab him
According to Dragon Ball Wiki, no. But I have played Dragon Ball Z: Budokai 2, and you can unlock him there by wishing for the fusion from Shenron.
