Answer
Each candidate for Holy Baptism is to be sponsored by one or more baptized persons. Sponsors of adults and older children present their candidates and thereby signify their endorsement of the candidates and their intention to support them by prayer and example in their Christian life. Sponsors of infants, commonly called godparents, present their candidates, make promises in their own names, and also take vows on behalf of their candidates.
It is fitting that parents be included among the godparents of their own children. Parents and godparents are to be instructed in the meaning of Baptism, in their duties to help the new Christians grow in the knowledge and love of God, and in their responsibilities as members of his Church.
There is no specification. You are free to be a be a Christian witness. However, the custom was that there be three godparents, one from the same gender and of the common church, the Episopal church. Godparents serve as a model for the church (Lutheran, Catholic, Episocpalian, etc.) that they are going to be witnessing to.
