go to the side of the man's house near the side where the water is then go to the wall then use your senses to find a digging spot that leads you inside the house and the sword will be on the couch in the house.

no
In my opinion skyward sword and twilight princess are very alike! Twilight princess is a bit longer though. (I recommend Twilight Princess because the plot is more interesting)
Yes
If by "second Twilight Princess" you mean Skyward Sword, no, it has not, or I would have already bought it. Also, Skyward Sword (in the chronological timeline order) occurs before Ocarina of Time and therefore before Twilight Princess as well, meaning that it is not a sequel, but a prequel.
Your sword cannot burn out. Only the shield can and it can be bought in most shops
Two: Skyward Sword and Twilight Princess.
Get next to it and pick it up.
You cut things with your sword or break pots
There isn't a sequel YES. it is skyward sword
