Yes, it does as there is a considerable electronegativity difference between given atoms.
NH3 is an asymmetrical compound.So it is exhibits.
No, it doesn't. Dipole moment is the measure polarity of a polar covalent bond
Yes. SO2 has a dipole moment of 1.62D SO3 has a dipole moment of 0. SO3, a trigonal molecule, has no dipole moment beacuse the bond dipoles cancel each other out. SO2 is bent and the bond dipoles do not cancel.
H-H bond has no dipole moment as both the atoms are the same.
Probably you are intending to question whether CCl4 has a dipole moment. if so the answer is no. it is because CCl4 is a symmetric molecule and hence even if each bond has a dipole moment, the algebraic sum of the dipole moments of all the four bonds cancel out resulting in zero dipole moment.
The bond dipole moment measure the polarity of a chemical bond.

No. H2 molecule does not have any dipole moment.
Generally if a molecule contains polar bonds and the bond dipole moments do not cancel each other out then that molecule will have an overall dipole moment. Bond dipoles arise when there is a significant difference in electronegativity between the atoms in the bond. There some cases such as phosphine PH3 where the lone pair can make a significant contribution to the molecular dipole moment.
Only a polar compound has a dipole moment. A non-polar substance cannot have a dipole moment.
A dipole moment is a mathematical product of the magnitude of a charge and the distance of the separation between charges. There are also many other types of dipole moments, such as transition, molecular, bond and electron.
There is a dipole moment on acetic acid. The O-H bond in acetic acid is highly polar, as is the double C=O bond. The arrangement is not symmetrical, so the dipoles do not cancel one another out.
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
