There is just one way to answer yes or no to all of those questions together, which yields one, and only one, password.
You have to use logic to try and find a way of answering the questions so that the number of passwords that fit all criteria are the minimum possible, you find the right answer when the number of possible passwords is 1 for a given yes or no sequence.
I recommend using a notepad or something to organize the rules and try to make connections between them.
when you think you have the answer, click on "Check solution here" and input what you think is the password.
