It really depends on the individual. Almost anyone can tolerate 2Gs for a
sustained period but moving about or lifting anything heavy would be
difficult. I think that the cutoff point for the average person (sustained)
is around 3.5Gs.

A young pilot in good physical condition ought to tolerate 5 Gs. With
specialized training, as was given to Spitfire pilots in WWII, 9 Gs is
possible.

That's strapped in, of course, and in the case of the Spitfire pilot,
he's grunting and straining for all he's worth.
