If she's the air-dash rush down kind of noel, I generally try to zone her out with j.C[m]. On counter-hit you can follow up with the combo of your choice to regain momentum and control. If she's drive mashing on you, IB her hits and tsubame her through her drive.
Best way to deal with her 5A is to keep zoning her so that she's just at the sweet spot for 5B[m] to connect but still be out of range for 5A.
