The author considers Darboux transformation of three nonlocal NLS equations and proper reduction conditions for the eigenfunctions. The formulae of n-fold solutions are represented by the ratio of determinants. According to the formulae, the author obtains explicit expressions of one- and twofold solutions of these nonlocal NLS equations, which are singular and have interesting structures. These types of solutions are new for these nonlocal NLS equations.
