For the derivative nonlinear Schrödinger equations DNLSI-DNLSIII, by using the dynamical system method, we investigate the exact explicit solutions with the form $ q(x, t)=\phi(\xi)\exp{[i(\kappa x-\omega t+\theta(\xi))]}, \xi=x-ct. $ In the given parameter regions, we present exact explicit parametric representations for more than 14 solutions.
