If I delete my eSIM profile from one phone, can I scan the eSIM QR code again into another phone?

No, once an eSIM profile is deleted from the phone, you cannot scan the same eSIM QR code into another phone. 

An eSIM QR code can be used and scanned only once. 

You’ll need to purchase a new eSIM QR code.

The legal stuff: We nor our upstream network partners are responsible for loss of carrier service as a result of an eSIM download wipe. If your phone’s eSIM line is currently active through a carrier other than us, you are responsible for obtaining and activating a new eSIM card from the carrier. You are responsible for any charges that your carrier may apply for a replacement eSIM card.
