I'm trying to replace 2009 RL lug nuts(90304-SJA-A91) with 2014 RLX lug nuts(90304-TK4-A01)

The lengths of the two lug nuts look different. The 2009 RL has a longer nut and the 2014 RLX has a shorter lug nut.
Is the lug nut of RLX correct for the genuine wheel bolts of 2009?

Also, both are ball seat lug nuts, but are they the same as R12?

Thank you for your reply in advance.

You could measure the thread protrusion from beyond your wheels and see if the shorter nuts have sufficient depth.

I believe the ball radius & thread speed should be standard, but the only way to verify is with one nut in each hand. That sounds wrong...
