You can add Menander, an early gnostic, to your list as well according to Justin Martyr in his First Apology:

And a man, Meander, also a Samaritan, of the town Capparetaea, a disciple of Simon, and inspired by devils, we know to have deceived many while he was in Antioch by his magical art.
... the Samaritans Simon and Menander, who did many mighty works by magic, and deceived many, and still keep them deceived.
I'm curious about that link between them, with both doing 'mighty works by magic'. And then Jesus passing through Samaria healing the lepers starting from Luke 17:11. It's sheer speculation to propose a link, but I think magic played a more important part in Christian origins than we think. "Samaria" may have been a hint with regards to that. In Justin's Dialogue with Trypho, he writes:
For that expression of Isaiah 'He shall take the power of Damascus and spoils of Samaria,' foretold that the power of the evil demon that dwelt in Damascus should be overcome by Christ as soon as He was born; and this is proved to have happened. For the Magi, who were held in bondage for the commission of all evil deeds through the power of that demon, by coming to worship Christ, shows that they have revolted from that dominion which held them captive; and this[dominion] the Scripture has showed us to reside in Damascus. Moreover, that sinful and unjust power is termed well in parable, Samaria.
In his First Apology, Justin writes about "we who formerly used magical arts", though I think he is referring to Christians generally rather than Samaritans like himself.
