The raising of Lazarus from the dead and the resurrection of Christ are usually considered to be the result of two different processes.
Lazarus’s being raised from the dead was a return to the state of life as he had before he had died; tradition holds Lazarus would live a more or less normal life and die again at the end of it.
The Resurrection of Jesus was believed to not be simply a return to the state of life that He had before death, but a rising to something better; a perfected human body, supernaturally transformed into something more than what it was before; an impassible body, infused with the glory of God, and existing forever without denigration or death.
Depending on who you mean by all the people that supposedly recommended one time (I assume you mean the ones mentioned in the Gospel of Matthew, after the Passion narrative), their resurrection is believed to be the result of Christ’s, for Christ is the “first fruit” but in no way meant to be the last.
So a Christian would be wrong in saying that Jesus is the only person who has returned from the dead, but His resurrection nonetheless represents a paradigm shift in Christian thought; there were miracles concerning people being raised from the dead before Christ, but Christ is the first in a kind of resurrection that fundamentally transforms human nature.
