If in attack position, yes, if in defense position, no. Any monster that isn't destroyed by battle has damage applied like normal. So, unless a monster can do piercing damage, you're safe.
Defender only prevents destruction, which would happen after it is attack and you lose life points.
No.
Use a Fusion Substitute Monster, or summon it by other means like Instant Fusion or Magical Scientist.
No on fairies, except DNA Surgery of course. Same goes for Plants, unless you Creature Swap a Naturia Pineapple?
okay thanks ^^ so that means arcana force 0 and the sanctuary in the sky are a great combo to protect yourself untill you get the cards you want?
oh and is there a card that forces your opponent to attack your monster? To attack Yubel actually
