ANSWER: I assume from the question that there are no elders where you worship. If there are, these men, of course, would have the authority to chair meetings. If there are no elders then one of the brethren should be appointed to chair the meeting. Having no authority, it would be his purpose to assure orderly transaction of the business at hand. Under no circumstances, should a woman chair such a meeting, unless it is in a congregation made up solely of women (I Timothy 2:11-12). To refer to a man chairing a meeting as the “chairman,” because it describes the function he is doing would not be wrong. However, allow me to suggest that you avoid using any title or expression that might elevate one brother over another. Nothing good can come from it, but will often create jealousies and division within a congregation. Even the words preacher, teacher, deacon, and elder are not to be used as titles. These are to be used simply to describe the function being done by individuals or groups. We all have names!

Let us use these!
