District Attorney Risa Vetri Ferman, along with the U.S. Attorney's Office, announced the charges on Friday.
The suspects were arrested back in January and February.
Investigators say the men were connected to a single victim, identified as "Victim #1."
The D.A. said the men would communicate to Victim #1 online and exchange nude images and videos with him.
In addition, three of the men met the boy in person and attempted to engage in sex acts with him, the D.A. said.
The suspects were identified as:
-Matthew Krapf, 43, of Collegeville, Pa. Investigators say he was arrested after he allegedly intended to meet Victim #1 for sex. However, an undercover detective was posing as the boy and Krapf was taken into custody.
The D.A. said Krapf had sex with five victims total and exchanged nude images and videos with one other victim. Some of the sexual encounters were recorded, investigators said. Krapf is being held on $1 million bail.
Meanwhile, a federal indictment also alleges Krapf met two minors for a sexual encounter, which he allegedly videotaped, photographed and posted online.
-Christopher Steele, 33, of New Castle, Del. Investigators say he travelled to Montgomery County to meet a minor for sex. The D.A. also said he exchanged nude images and videos with a minor. He is being held on $1 million bail.
