If humans were to travel from earth to another planet that was an exoplanet 5 times the mass of Jupiter, would they be able to survive?
No.
Jupiter's mass is 318x that of Earth, and you want 5x that, which gives about 1600x Earth's mass.
That much mass in an rocky planet requires (using the formula for the volume of a sphere V=4/3Àr^3, and presuming that the planet has the density of Earth) a radius 7.25x larger than Earth's.
Plugging the 1600x mass and 7.25x larger radius into Newton's universal law of gravitation (F = Gm1m2/r^2) while taking Earth's gravity as "1", such a planet's surface gravity would be 30.5x grater than Earth's.
You'd be crushed by your own mass.
