Most memorably, in Act 3, scene 3 when he comes across Claudius apparently at his prayers.
Hamlet finds Claudius praying for forgiveness after the play. He decides that if he were to kill Claudius at that moment, Claudius would go to heaven rather than to hell. Hamlet decides to wait until he finds Claudius sinning, in order to kill him.
Claudius is the king, right? That means he's surrounded by bodyguards all the time. You can't just march up to him with a knife in your hand. Hamlet has to find the right moment before he can kill Claudius.
Well, the basic reason is that they're not in the Chapel. The setting is Claudius's private room, the King's Room. That's stated in the play dialogue. Guildenstern says it: "(the king) is in his retirement..." It's reference to the place Claudius retires for the night, his private quarters. When Claudius left the 'Mousetrap' play, he went to his own room. Claudius prays during the scene, and apparently the idea of praying has led some people to think the scene is in the Chapel, however, the actual play dialogue tells us otherwise. People don't have to be in a chapel to pray, and many people pray in their own rooms, of course, which is what Claudius does. Hamlet is discouraged from killing Claudius because he finds Claudius praying. Hamlet is afraid that if he kills Claudius at prayer, Claudius's soul will go straight to Heaven. However, the Ghost said, or very strongly implied, that the soul of Hamlet's father was in Purgatory. Hamlet doesn't see it as fair, that he could send Claudius to Heaven, when his own father is in Purgatory. Hamlet decides to wait for another opportunity later, when there's less chance of sending Claudius's soul to Heaven.
Claudius will be killed, but his mother will be spared.

Claudius was hamlets Uncle and later became his stepfather because his mother Queen Gertrude married Hamlets uncle "Claudius".
King Claudius believes that Hamlet is a threat to him because Hamlet killed Polonius, who was hiding behind the curtains and Hamlet and actually thought it was Claudius. Claudius feels threatened and in danger by Hamlets behavior and as a precaution sends him to England, where Claudius also sends a letter to kill Hamlet upon arrival in England.

Claudius knew. That's why he conspired with Laertes to kill Hamlet first.
He is talking about Claudius and about killing him.
Hamlet hesitates killing King Claudius, because at the time Claudius was praying for forgiveness and if Hamlet killed him then Claudius would go to heaven and Hamlet to Hell. But his chance to kill him without doing wrong was still there, he just didn't stick around long enough to hear the rest of the agony. Claudius amended "My words fly up, my thoughts remain below; Words without thoughts never to heaven go." Hamlet missed his opportunity to save the lives of many and that would made for a short and heroic play without so much tragedy. Less entertaining too.
No, Claudius is Danish and the Ptolemies are Egyptian. There is nobody called Ptolemy in the play Hamlet.

Hamlet decides to kill Claudius, but first he needs to confirm that what the ghost of his father said was true. So, he devises the play to see if Claudius' guilty conscience will betray him. His suspicion confirmed, he almost murders him him the chapel, but when he sees that Claudius is praying, Hamlet spares him until he can kill Claudius at such a time that it will condemn his soul. The irony is: we learn in soliloquy that Claudius is not able to pray.
Claudius and Laertes plot to kill Hamlet.
I guess you could say that Hamlet's first attempt to kill Claudius was when he stabbed Polonius, since he says "I took thee for thy better." At that time Claudius was probably still downstairs somewhere.
They have different motives. Claudius wants to keep his crime a secret, and Laertes wants revenge for his father's death.
