بسم الله الرحمن الرحيم
There is no harm in keeping the name Taiba, Kausar, Shahnaz, Aqib, Qurra, Dihya. Don’t keep the name Ifrah, Illiyen, Laiya. If you have kept then change it. Just make firm intention not to keep in future. It is not necessary to do regular taubah for the same.
Allah knows Best!
