The objects are placed based on sequential order in a sequence diagram.
The vertical dashed lines are the "lifeline" that shows the existence of the objects or actors over time; moving down the lifeline means more time is passing.
"Request PIN" is a message, and it is not a reply message; because "Request PIN" is not replying to an earlier message and is requesting information rather than responding
