I think first you have to answer how a single program generates a
single 1p reality. There is no consensus yet on how to do this,
although there are theories. But let's say you have a working theory
of how a program can generate a 1p reality. Then you can modify that
program to generate additional realities simultaneously.

Check out this incredible story of a ragtime piano player named Bob
Milne who can imagine up to four orchestras playing music at the same
time. Neuroscientists verified his abilities.
 This takes no effort for him and the music as it is playing in his
head does not "clash".

I know Bruno already answered this but I will attempt it too. The
physics and in general the world we observe is the stable measure of
realities generated by the UD that include the computational state we
are currently in. Since each of these traces in the UD contains "me",
each "me" is sharing the experience of each reality. They are all 1p
experiences, and yet they are all shared by each version of me being
traced by the UD.

When it comes to others, you are correct, that what is sharable must
be negotiated through language. I don't think btw the result of that
shared process is necessarily "objective reality", I think a more
accurate phrase would be either "working objective reality" (as in, we
proceed *as if* there is an objective reality) or perhaps
"intersubjective reality".  I'm guessing that is why you used scared
quotes around it...
