Hi Ashish,
This is a bit involved for a support-related question. Usually help with setting up complex, highly use-case specific functionality starts to move into the area of paid consulting. However, this is a good example of how to use Variables and Conditions in a real world example, and we think it would be helpful to others as well.
Basically you need to keep count of how many buttons were clicked (using a variable), and then a series of conditional actions to check to see what the count is, and which people have already been disabled, so that you only show the text for the right people. Here is a video that shows you how to set this up:
