Results of investigations of six poorly studied or unstudied open clusters are presented. The ages, interstellar reddenings, distances, and structural parameters were derived based on BV photometry combined with the near-infrared JHKS data. The mass functions were analyzed for four objects and total masses, number of members, and dynamical-evolution parameters were estimated. Berkeley 95 was found to be an extremely young stellar cluster. King 17 and King 18 turned out to be an intermediate-age objects. Czernik 21, Czernik 38, and Juchert 11 were found to be old stellar ensembles of the age of about 1 Gyr old or older. Czernik 38 is located in the Sagittarius Arm while the remaining clusters belong to the Perseus Arm.
