Yes, that is allowed. You cannot, however, attack and then change to defense in the same turn.
Yes. The 'cannot change battle position' limitation is only for manual changes such as flip summons or putting a monster into attack mode. The monster's position can still freely be changed by effects.
A monster in face-down Attack position is unable to declare attacks. It can be flipped or Flip Summoned, both actions will switch it into face-up Attack position. It can also have its battle position change by the controlling player, switching it from face-down Attack position to face-down Defence position.
No, a monster cannot manually change battle position on the turn it was special summoned, though it can be changed by an effect.
A monster can't manually change battle position on the turn it declared an attack, but it can still be flipped face-down by an effect. Golem Sentry can attack, then activate its effect in main phase 2 and flip itself face down.
Yes, that is allowed. You cannot, however, attack and then change to defense in the same turn.
Yes, if you control a monster in defense mode and it is changed to attack mode during the Battle Phase by a card effect, it can attack. The "Zero Gravity" Trap card is an example of a card that can switch your monsters' battle position during the Battle Phase. But if the monster already attacked that turn, was switched to defense mode, then changed to attack mode again by an effect, it cannot attack again on that same turn.
Yes. The battle phase hadn't ended yet, and since the new monster hadn't attacked that turn, it can now declare an attack too.
When the number of the monster on the "defenders" side of the field changes, a replay battle occurs. Then the "attacker" can choose to continue with the attack, change the attack's target, or cancel the attack altogether.

The monster is flipped into face-up defense position and any battle damage that occurs is calculated. Afterwards the monster that was attacked remains on the field and is not sent to the Graveyard.Examples of monsters that cannot be destroyed in battle are Spirit Reaper and Marshmallon.If a monster attacks with an effect that enables it to deal damage equal to the difference in its ATK and the defending monster's DEF (like Twin-Sword Marauder or a monster equipped with Big Bang Shot), the damage is calculated but the monster is still not destroyed in battle.

You simply cast the spell from the dark wizards named Morph. you change into something stronger at each level. Change into up to 7 monsters. The monster attack will be added onto your attack along with half of other remaining stats into yours. Last up to about a minute at all level. While you morphed the monster will not attack you unless you attack that particular monster, and that particular monster is only one in the map to attack you back. And of course, higher the skill charge the stronger the morphed monster you turn into.
No. If you could, it wouldn't make sense for there to be rules that you can only summon face-up monsters in attack position, as you would be able to immediately change them into defense position anyways.
It's impossible! You can change the colour but you can't change the species of your monster during the game.
