Not exactly. You can proceed from Main Phase 1 to the End Phase if you don't wish to have a battle phase, that is valid. You will skip the Battle Phase and Main Phase 2. But if you DO have a Battle Phase, then you must also have a Main Phase 2. A turn player can ask the opponent if it's ok to move to the end phase from the battle phase if he doesn't want to use Main Phase 2. That allows the opponent opportunity to say no, if they wished to activate something there. But the phase is not being skipped, in the same sense as the example above.
Yes, of course. Quickplay spells can be activated at most times during the battle phase and up to the end phase, the spell speed 1 ones can be activated in Main Phase 2.
For Polymerization, the Fusion Components/ Fusion Material Monsters can either be in your hand or on the field, or a combination of both.
Magical hats can only be used during your opponent's battle phase. Seeing as they can't flip their monsters during their battle phase, no. However, if your opponent does activate a spell or trap card during the battle phase, you can use Magical hats and protect your monsters. Overall, yes. You can use magical hats to protect your monsters from targeting effects as long as it's during your opponent's battle phase.
Yes. If you have Ultimate Offering, you can use the effect during the opponent's battle phase. You can use it to do two Normal Summons, yes, you can perform a tribute summon if you wish.
No. Because Polymerization is not a Quick-Play Spell Card, it cannot be activated in the Battle Phase.If you attacked with the Fusion Material Monsters, you could not play Polymerization as it would still be the Battle Phase. As a result, you must end your Battle Phase, and switch to your Main Phase 2 to activate Polymerization. Even if you activated it during this phase, it would have already been after your Battle Phase; and because you can only have one Battle Phase per turn, this strategy would not work.You could, however, use Super Polymerization as an alternative. Because it is a Quick-Play Spell Card, it would fit into this strategy.Super PolymerizationSPELL/Quick-PlayDiscard 1 card. Send, from either side of the field to the Graveyard, Fusion Material Monsters that are listed on a Fusion Monster Card, and Special Summon that monster from your Extra Deck. (This Special Summon is treated as a Fusion Summon.) Spells, Traps, and Effect Monsters' effects cannot be activated in response to this card's activation.

yes you can use his effect in battle phase
The +200 ATK bonus is applied only 'during your battle phase', this is a continuous effect that does not use the chain. As soon as the battle phase ends, the +200ATK ceases to apply, but will be reapplied during your next battle phase. So say you have a monster with 1700 attack, it will ONLY have 1900 (+200) attack when you're in your battle phase and when you're back in your main phase 2 or end phase it goes back down to 1700 (-200). One thing to note is that you'll get the +200 attack during BOTH your own battle phase AND ALSO your opponent's battle phase.
Yes, of course. Quickplay spells can be activated at most times during the battle phase and up to the end phase, the spell speed 1 ones can be activated in Main Phase 2.
Depends. If you're talking about their ability to tag back into the deck and summon a new one, remember this happens during the 'end of the battle phase' and as such, no more attacks can be decared at or after this time.
Timeater will prevent them having a Main Phase 1, and Chacu Challhua will prevent them from having a battle phase. As per regular turn structure, you must enter your battle phase if you want to have a Main Phase 2, so they will not get one in this case. The opponent's turn will therefore go Draw, Standby, End Phase.
Yes, Stardust Dragon can activate its negation Quick Effect in the Battle Phase, and even the Damage Step.
Even if the turn player makes no game actions (apart from his turn draw), he still has to pass Priority to his opponent each time he wants a phase to end. The opponent could activate his Royal Decree during any of these times, so, he could do it in the draw phase, standby phase, main phase 1, and end phase (the turn player can proceed straight from main phase 1 to the end phase. If the opponent did have a card that could only be used in the battle phase, here, he would not be given chance to use it).
You can only use it on Wi-Fi or in Battle Frontier. It asks you at the end of the battle if you wish to record your battle.
You can use it during the Battle Phase, but not during the Damage Step of the Battle Phase. So if you attacked, and an opponent used Mirror Force, then you can chain Trap Stun, as you are not yet in the Damage Step. However if the Damage Step was entered and a player used Nordic Relic Megingjord, you could not chain Trap Stun to it.
