LiCl has partly covalent character whereas halides of other metals are ionic in nature. If anion remains the same, the Lattice energy of ionic compound decreases with increase of ionic radius of cation. So, sodium chloride shall have highest lattice energy.

Higher is the lattice energy, the higher will be melting point hence NaCl has highest melting point.
