Can I ask Senior title

I have had senior title for ten years. For unknown reason, all people fired at my time had no senior title. So I didn't bother to ask. Recently I noticed a few has senior title from outlook. I am the only female among the 16 people in the team. I sat far away from team and  rarely socialize with them. I believe I have been doing more areas than most people. I know it is not time for company review yet.

But how did they get senior titles? How should I ask?

Thanks for advice
