In case of Boruto and Himawari whiskers don't necessary mean Kurama's influence. They can simply be a inherited physical trait. In case of Naruto they came from Kurama because Kushina was a jinchuuriki and the body transfers a chakra to baby during pregnancy, so some of fox' chakra could slip into Naruto then. Hinata is not a jinchuriki, when she was pregnant only her chakra was transferred to baby growing in her womb.
