The first two sound native UK to me, but I'm a yank.
I can clock the third one as foreign because she overdoes our rhotic r which isn't uncommon for assiduous US-English learners.
No idea where they're all from... but I will say blended accents are so delicious to my ear; like a Korean who learned English in Texas or (much more common), a German who learned UK pronunciation.
[And, yes, I know it's bias to not hear one's native accent as an accent.]
