Antique Bar Pins & Cufflinks

I have these five items and have listed a number on each. My great aunt was an antique dealer and these are items that I received when she passed away. I wanted to find out more about them and see what their values might be. There is very little info on each, but I will include what I know. The first three are the bar pins. #1 has a tag saying it is 14k gold. #2 says something along the lines of CalB or CaB. #5 says it is a 14k cufflink.
I have much more from her, but these few always stood out. I hope to get everything passed down appraised for insurance purposes in the future, but need to find someone in my area able to do that.
