1 sn Epaphras is probably a shortened form of the name Epaphroditus. This is probably the same individual whom Paul spoke of as “my brother, coworker, and fellow soldier” in Phil 2:25 (see also Phil 4:18). He is also mentioned in Col 1:7 and 4:12, where he is a founder of the church in Colossae (BDAG 360 s.v. ᾿Επαφρᾶς).
2 sn Aristarchus accompanied Paul on his collection-journey when Paul left for Rome in Acts 27:2. He is also mentioned as a fellow prisoner in Col 4:10.
3 sn Demas is most likely the same individual mentioned by the Apostle Paul in 2 Tim 4:10. Apparently, he later on abandoned the faith because of his love of the world.
