Collection Mixed Pins

I have had these pins for some years now & have recently come across them. All I can say they are varying ages & makes. The (N) has clear stones that shine under light. I'm not sure if they are Lapel pins, scarf pins or a hat pin if anyone has any information on any of these it would be great. Merry Christmas. I believe the floral pins may be made of clay from what I have seen today looking around. Still no idea of age.
