Is the repentance and remorse of an oppressor who has repented and sought forgiveness accepted, even if the oppressed refuse to forgive him and curse him, with some of them demanding compensation for forgiveness, and will harm befall the oppressor and his family due to the prayers of the oppressed, despite his repentance?

One must be wary of relationships between men and non-mahram women. If you have wronged these girls, then you must perform sincere repentance and try to seek their forgiveness. If you apologize to them, you have fulfilled your obligation, and they have no right to refuse your apology. Sincere repentance protects one from harm. Lying is forbidden except in cases of necessity.
