Homework Statement

I am assigning m/z peaks on a mass spectrum, and there are 3 peaks not on the chart given by the instructor, and I was wondering if anyone can help me determined their identities. The peaks I am unsure of are found at 95 m/z, 109 m/z, and 123 m/z; I already figured out the rest of them. Thanks!
