but could be amu or g/mol, depending on context.Molar mass uses g/mol.Often, the word weight is used when amu is desired, as in relative atomic weight and mass is used when g/mol is the desired unit.......
Do all of them have a unit?

"Do all of them have a unit?"

Yes. However, there is a difference between usage of amu and g/mol (other than the fact that amu is used for single atoms or molecules and g/mol is used for macroscopic amounts).

Relative atomic mass usually uses amu. However, sometimes a person ignores usual usage and writes g/mol when using the term "relative atomic mass."

Relative molecular mass isn't seen that much, but could be amu or g/mol, depending on context.

Molar mass uses g/mol.

Often, the word weight is used when amu is desired, as in "relative atomic weight" and mass is used when g/mol is the desired unit.

amu = atomic mass units
