How do vibrational, translational, and vibrational motion relate to entropy and enthalpy?

They relate because through this molecular motion in each one is how the molecule can store energy. This motion results in the greater the number of possible microstates which then leads to higher the entropy.

Are entropy and enthalpy directly proportional?

They aren't directly proportional; however, when vibrational, translational, and rotational energies are stored within a molecule as the internal energy, U, this could indicate the amount of enthalpy or entropy within that molecule or system.
