Yes. (Mark 16:20, John 3:2, Acts 2:22)
Therefore many other signs Jesus also performed in the presence of the disciples, which are not written in this book;
John 20:30 NASB
No. (Matthew 16:4, Mark 8:12, Luke 11:29)
39 But He answered and said to them, “An evil and adulterous generation craves for a sign; and yet no sign will be given to it but the sign of Jonah the prophet;
40 for just as Jonah was three days and three nights in the belly of the sea monster, so will the Son of Man be three days and three nights in the heart of the earth…”
Matthew 12:39-40 NASB
No sign?
In three Gospels the question came to Jesus to do a miracle, a sign. And in all occasions Jesus was disgusted about it. Why?
The power of unbelief
Jesus was disgusted as the question came in all occasions from Pharisees who didn’t want to believe in Him. Even on the cross they shouted “Come down from the cross that we may believe!” If someone has decided to reject the faith for any reason one will reject any aspect of that faith every time. So did the Pharisees in general and their question was a sign of their unbelief. If they had looked around, had spoken with the healed, they would have known enough. Jesus called them the generation that would not be given a sign. Apart from one sign: after his departure from life they would be confronted with his resurrection. Just as Jonah was three days and nights in the great fish, Jesus would be in the grave for only three days and nights.
Meanings of generation
The critic sees a discrepancy in the information in all the Gospels that Jesus did many signs and the few sayings of Jesus that he didn’t want to give a sign to this (evil) generation. The critic overlooks the two meanings of the word generation. 1. (vertical generation) Descendants of someone or of something; 2. (horizontal generation) All people belonging to a certain period of time (often: those who live now).
Separation
Jesus spoke to the Pharisees as descendants of evil, who had hardened their heart (Mark 8:17); meaning 1. Here, Jesus didn’t use the word referring to all the people of Israel in whose midst he performed his miracles; meaning 2.
So there can be no misunderstanding. The Pharisees would never see any miracle, due to their hardened heart and not as a result of Jesus’ inability. They had forgotten what Isaiah (59:2) had said: “But your iniquities have made a separation between you and your God.”
At the right hand of God
After Jesus’ resurrection the Pharisees would be confronted with a new generation of people that would confess about Jesus being alive at the right hand of God. And this generation of believers would never disappear on earth. Just as nobody had controlled Jonah being in the great fish, as was reported in ‘their law’. In the same way there would be no eyewitness when Jesus actually resurrected and yet forever it is God’s sign for mankind for those who believe.
