You can't your probably thinking of the Iron Golem. He's not a Villager. But you can make him, you need 4 iron blocks and a pumpkin. you put 2 iron blocks pointing up and then 1 iron block on each side, then you put the pumpkin on top, and you have an iron golem to protect you!
No. That is impossible.
No, villagers do not eat.
Villagers aren't available on Minecraft P.E. yet.
There are villagers in the full version of Minecraft and the Minecraft demo. However there are no villagers in the Classic version of Minecraft, but it is possible for a server to create AI controlled entities (which mostly just stand there).
You can't make villagers without mods. They spawn naturally in so-called NPC villages randomly placed on the map.
you can't. however, you can trade villagers for some
u cannot breed villagers

Villagers are never hostile towards you, unless they are zombies or you have a mod that causes villagers to attack you
You go to a village and make a house, and then two people will come to the house go in and then they will make kids!
because emeralds were added to be able to trade with the villagers
