As long as you summoned it with Monster Reborn in main phase 1, then yes, of course. If you summoned it in main phase 2, you cannot attack because you have already passed the battle phase.
Monsters can only 'manually' change battle position in your main phases. If you want to change them during the battle phase, you will have to do it by a card effect.
As long as you are Special Summoning before, or during the Battle Phase, then yes, that monster can attack.
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!! Because you have both a main phase 1 and a main phase 2. If you do not summon a monster in main phase 1, enter your battle phase, complete your battle phase, then enter your main phase 2 and you can summon a monster with 4 stars or less unless it has a special effect or tribute the monster that already attacked. Unfortunately you will not be able to attack with the new monster until the next turn, but hey, thems the breaks.

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.

What Confusion Chaff Does is When you are about to take a Second Direct attack During the Same Battle Phase, you can play this card, and The monster that is attacking and the monster that has attacked (The one that gave you the First Direct Attack) are forced to battle.
