5. Lie on your face on the floor with your hands by your sides. (What about this one?)

One has (usually) two hands and two sides. "sides" is appropriate. In #3, "both" is redundant. We only have two sides.
"by" and "on" are synonymous in this context.

#5 is fine.
Actually, "by" and "on" are not exactly synonymous. "by" doesn't mean touching your sides; "on" does.
