Regrettably, no sharing of any kind.
But you can change your plans as often as you want based on your individual consumption and usage requirements.
You can also share the same payment card information so that payments are taken from the same payment card.
I suppose, if you’re somewhat near to each other, you could also set up a hotspot from one device to the other device/account to utilize their data if ones data is depleted.
