Banquo likely would have shown a mix of disbelief, caution, and skepticism if he had been told he would be king. Due to his noble character and loyalty to Duncan, he might have rejected any idea of harming the king to seize the throne for himself, unlike Macbeth who succumbed to ambition and murdered Duncan.
In both cases, the ghost that appears in Macbeth is summoned by the guilt and inner turmoil of Macbeth himself. The ghost of Banquo is a manifestation of Macbeth's guilt over his role in Banquo's murder, while the ghost of Lady Macbeth represents his guilt over her death and his descent into madness.
