If you do not want to boot from the disk: yes.
If you want it bootable it may be necessary to install new boot code
(gpt biosboot....).

You did not show disklabel output, but you said no swap. Otherwise you
will have to manually adjust for the disklabel contents (which get
lost in the migration).

No, unless you want to share the disk with other operating systems and
create additional "foreign" partitions on it.

Yes. The critical parts (with gpt defaults, can be fine tuned manually)
are 34 free sectors before the first partition and 33 sectors at the end
of the disk. Both are available on your disk.
