Thorin Oakenshield, or Gandalf, depending on your perspective.
Legolas, Gimli, Gandalf, Bilbo, Frodo, Sauron, Sarumon, Aragorn, Borimir, and lots of others.
Bilbo Baggins
Gandalf.
Gandalf surprised Bilbo and he was foreshadowing the future
Gandalf noticed the ring turning Bilbo crazy so he forced him to give it up and leave it behind
the person who praised bilbo was Gandalf.
Yes, the wizard(Gandalf) likes Bilbo very much. It is by the will of Gandalf that Bilbo comes along with the dwarves for the quest. His concern for Bilbo can be seen when all the dwarves come out from goblin's cave but Bilbo remains behind. Gandalf continues to visit Bilbo even after the end of dwarves quest.
Gandalf is much older than Bilbo no matter how you count it. Bilbo Baggins was born in the year 2890 of the Third Age. Gandalf, in his current form of an old man, arrived in Middle-earth in the 11th century T.A.; but he himself almost certainly was already there before the physical world was created.
