I've finished the game, I'm stuck with some quests, Side Quests -> Resolutions ... I managed to visit Ragash but I didn't find Visit Vera, how do I do that?

In Side Quests -> Nyx's Costumes, I found Topaz, and Emerald and Quartz, just update?

I have Rose Quests -> Menage a Trois locked, I found candle and wine, I went to Rose's house with a date with Mary but after that it locked, I don't know how to finish this quest, how do I do it?
