What does Luke 19:5 mean?

By placing the story of Zacchaeus (Luke 19:1–4) right after the story of the blind beggar, Luke shows how the two are strikingly similar, despite their social disparity (Luke 18:35–43; 19:6–10):

Both are social outcasts. People in Jesus' era often believed handicaps such as blindness were God's punishment for sin (John 9:2). The people also hated tax collectors.

Both men require other people's money. The blind man begged for alms. Zacchaeus, as a tax collector, took taxes with the authority of the Roman government—and then took more for his own commission.

Neither man can see Jesus: the blind man had to shout for Jesus' attention and Zacchaeus needed to climb a tree.

Jesus called both men to Him.

Both men face opposition. the crowd tried to shush the blind man so Jesus wouldn't hear him. A different crowd doesn't believe a tax collector has the right to host a revered teacher.

Jesus opens both their eyes. The blind man can now see physically. Zacchaeus gains the ability to recognize his fallen spiritual state.

Both men react appropriately. The blind man follows Jesus. Zacchaeus returns the money he stole, with generous compensation of his own.

The text doesn't explain how Jesus knows Zacchaeus' name. It's possible this was something perceived through the Holy Spirit. Maybe Jesus had heard of the unusually small tax collector of Jericho. Or the name may have come up from the crowd or others as Jesus passed by. Jesus says He "must" stay with Zacchaeus; it is a necessity. Jesus' request is bold to Western eyes, but as is common in the Middle East, Zacchaeus is honored to host.
