The Bible says nothing about this. The closest you can come in Scripture is Luke 16:19-31
19 “There was a rich man who was dressed in purple and fine linen and
lived in luxury every day. 20 At his gate was laid a beggar named
Lazarus, covered with sores 21 and longing to eat what fell from the
rich man’s table. Even the dogs came and licked his sores.
22 “The time came when the beggar died and the angels carried him to
Abraham’s side. The rich man also died and was buried. 23 In Hades,
where he was in torment, he looked up and saw Abraham far away, with
Lazarus by his side. 24 So he called to him, ‘Father Abraham, have
pity on me and send Lazarus to dip the tip of his finger in water and
cool my tongue, because I am in agony in this fire.’
25 “But Abraham replied, ‘Son, remember that in your lifetime you
received your good things, while Lazarus received bad things, but now
he is comforted here and you are in agony. 26 And besides all this,
between us and you a great chasm has been set in place, so that those
who want to go from here to you cannot, nor can anyone cross over from
there to us.’
27 “He answered, ‘Then I beg you, father, send Lazarus to my family,
28 for I have five brothers. Let him warn them, so that they will not
also come to this place of torment.’
29 “Abraham replied, ‘They have Moses and the Prophets; let them
listen to them.’
30 “‘No, father Abraham,’ he said, ‘but if someone from the dead goes
to them, they will repent.’
31 “He said to him, ‘If they do not listen to Moses and the Prophets,
they will not be convinced even if someone rises from the dead.’”
Some claim that this man can see his family, but the text says nothing of the sort.
Other references are used to support the claim, but all are equally weak. Nothing in Scripture indicates that we will be able to see our loved ones from Heaven.
It is, of course, possible that they can. Scripture doesn't give every detail of every truth. Absence of evidence isn't evidence of absence, but such an idea doesn't originate from the Bible, or any Biblical teaching.
