Luke 23:
Some believe that the dead have a conscious spirit existence in Sheol/Hades as in the story of The Rich Man and Lazarus. I think that is a parable meant to be symbolic and not physical.
I don't think our dead loved ones can presently see us from heaven.
Another Lazarus was not a parable but a real person. He was the brother of Mary and Martha. He was dead for 4 days (John 11:39). I don't think he would appreciate Jesus resurrecting him while he was enjoying his time in heaven.

i.e., the second coming on the last day of the current universe39 One of the criminals who were hanged railed at him, saying, “Are you not the Christ? Save yourself and us!” 40 But the other rebuked him, saying, “Do you not fear God, since you are under the same sentence of condemnation? 41 And we indeed justly, for we are receiving the due reward of our deeds; but this man has done nothing wrong.” 42And he said, “Jesus, remember me when you come into your kingdom.”
This criminal died on his last day on Earth. When a person dies, time stops with respect to him (e.g., gravitational time dilation). When he is resurrected, he will be with Jesus in paradise. To him, it will be the same day: today, i.e., the last day of the old universe. From his perspective and God's perspective, there wasn't even any waiting. His today is the same as his last day on the old earth and is the same as the last day of the universe after he is resurrected, John 6:43 Jesus answered him, “Truly I tell you, today you will be with me in paradise.”
In terms of physics, a wormhole (Einstein-Rosen bridge) is a structure that connects two black holes. It is possible that an object that falls into one end of a wormhole can travel through it and come out at the other end at a different point in space-time.40 For my Father’s will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise them up at the last day.”
