List of unnamed photonic lifeforms.
After Iden delivered them from the Nuu'Bari mining vessel he wanted them to join his rebellion, but the first hologram only asked for input. Iden was unhappy to learn that they were non-sentient holograms and had very low matrices that could not be enhanced. (VOY: "Flesh and Blood")
These two photonic aliens along with the rest of their species mistakenly believed that the Captain Proton holodeck program was real and were at war with Doctor Chaotica. They assumed Human form but were taken prisoners by Doctor Chaotica and his henchmen. After the second alien was killed by Chaotica, the first one returned to the other beings. He later took again Human form and met with The Doctor, who was posing as the President of Earth. The Doctor convinced the alien that they should join forces to defeat Chaotica. The alien agreed and returned to his realm, termed the fifth dimension by the program, once Chaotica had been defeated. (VOY: "Bride of Chaotica!")
Members of Iden's Rebellion
These holographic aliens were part of Iden's rebellion against the Hirogen hunters. In 2377, these holograms, which were previously created by the programmer Donik as coequal prey with enhanced memory, comprehensive tactical algorithms, and expandable data processing, gained knowledge about themselves and formed a rebellion against their hunters, led by the Bajoran Iden. Together with Iden, Kejal, and Weiss, they escaped from the Hirogen training facility by using a Hirogen ship, with the goal of creating their own colony and living their own lives.

Holographic Starfleet officers
The first three holographic Starfleet officers and Weiss were hunted down by two Hirogen hunters in a Hirogen training facility. They've covered in a lake and surprised the two Hirogen by firing out of this lake. The two Hirogen were killed during this maneuver. Later they joined Iden's Rebellion and worked on the abducted Hirogen ship.
The third holographic Starfleet officer also joined Iden's rebellion and worked as nurse for the wounded holograms aboard the Hirogen ship.
The fourth holographic Starfleet officer was wounded during a shootout with the Hirogen hunters and suffered from pain caused by a bloody head wound.
The fifth and sixth holographic Starfleet officers were shot down by a Hirogen hunter aboard the Hirogen training facility. This scenario was a memory of a Cardassian hologram, experienced by The Doctor. (VOY: "Flesh and Blood")
