Is it permissible to go shopping while transferring from DLR to Jubilee?

Yes, but if you spend more than 15 mins outside the barriers it counts
as 2 separate journeys.

What happens if, after doing your shopping but before entering the
Jubilee station, your plans change and you have to go back to DLR?

I think you get charged for two journeys even if there's only a few
seconds between touching out and touching back in.

(Come to think of it, if you're making that transfer, are you supposed
to touch out at the DLR station or not? And in the opposite direction,
are you supposed to touch in?)

The rules say that you should, yes. I think the general advice is to
touch in and out every time you enter/leave the Oyster fares area (ie
TfL property), although this gets very complicated at places like
Stratford.
