overwatch
When Hanzo activates his ultimate he fires an arrow with the range of 5 meters, in the case that an enemy hero goes in front of him will it damage/kill them?
if he kill them what will the kill bar indicate, a normal kill(normal arrow shot) or ultimate kill(Dragonstrike)?
Melee attack does 30 damage and Winston's Tesla does 60 DPS
A melee attack takes one second, so no, it's not better to use melee - stick with the gun.
Shoot the ground directly in front of the opponent. Since its a scatter effect it will work best against big targets. It's a little tricky to do, as the idea is that the arrow will impact the ground so close to the opponent that all the scattered arrows don't have a chance to go into anywhere else. I would recommend loading up the training grounds and trying it on the training dummies to get a feel for how it works.
Edit: Here's a crude drawing of what you're trying to do. The red line is the scatter arrow. It's like you're firing a shotgun shell at the point of impact so the closer the impact point, the more effective it is.

Yes, the arrow fired by Hanzo to activate his ultimate can kill enemy players.
The kill feed will indicate a kill with his ultimate as shown in the following video at around 12 seconds:
