The owner of the copyright in a creative work is the person who created that work, except under circumstances that don't seem to apply here from what you said. You cannot use their photographs without their permission - to use them is copyright infringement. However, they may be limited in how they can use the photographs if they portray you or your group under your right of publicity. Rights of publicity prohibit the use of another person's likeness or image for commercial purposes without their permission. There are exceptions to the right of publicity, and these rights and exceptions vary from state to state. Consult an attorney who is knowledgeable in these fields to see if you can prevent them from using their own photographs of you in this manner.
