If you are unhappy with your salary you should definitely discuss it with your boss.
However, I would suggest not bringing up what other people in the company are making or what raises they might have recently received. That is irrelevant, it isn't a competition or a parent handing out allowances to all of their children. Your salary is the negotiated amount based on your value to the company and what you reasonably can get in the marketplace.
So when you ask for a raise you are re-entering that negotiation and need to have something new to bring to the table. That is, why are you worth more now than when you previously agreed to work for your current salary? Your best bet is to demonstrate that you have gained new experience/skills that are valuable to the employer or that you have taken on greater responsibility.
One other thing. I'd avoid the line of argument that raises are necessary to keep up with inflation. While this is often true (not so much this year), you really need to frame the discussion in terms of the extra value you are providing, not in terms of your own financial situation.
Update based on comments:
The only inflation that matters in this discussion is that for labor prices for your specific job. Those tend to jump up AND DOWN quite a bit over the years. If you want to make the inflation argument you should be willing to take a pay cut whenever the job market starts tanking. The price of eggs and gas are immaterial from the perspective of your employment contract.
