The creature card you reveal during the draft can be another Noble Banneret. That second Noble Banneret will then be face up for a future creature card to be revealed. If Noble Banneret is one of the names you noted, a Noble Banneret that's the only creature you control will get +1/+1 and have lifelink.

If you gain control of a Noble Banneret, but you didn't draft one, there will be no applicable noted names. It won't get +1/+1 or have lifelink.
