Does my new Honda have a grace period for returns?

Added (1). It's a new lease.

Almost NOBODY has a grace period - That's an old wives tale. Now, occasionally a dealer will have a sale & give you that option, but he will make sure everybody knows it & will advertise the heck out of it. The other 99.5% of the time, once the last paper is signed, it's yours, period.

Your an adult now, you had all the time in the world to think about a lease before you signed the contract. Do-overs are for children, but why are you so afraid to ask the Honda dealership?

No. As long as you've signed the papers and taken delivery of the vehicle, the deal is done and there's no grace period unless the dealer gave you a written return policy. It's the same with a loan, lease, or cash purchase and for both new and used vehicles.

Probably not.
