Target Audience Research (initial ideas)

I have came up with some questions which I could ask in my questionnaire. I plan to make the questionnaire on survey monkey and use multiple choice questions.

• Age : I plan to aim my magazine at 15-25 year olds therefore I know to ignore irrelevant data that comes from another target audience.
• Gender : I plan to aim my magazine at females so I will take this into consideration when looking at the data from male participants. 
• Do you like singer/songwriter mainstream music? : If the answer is no, then I will take this in to consideration because I know that this person is not a part of my target audience, so their data won't be relevant. 
• What font would be most appropriate? This will help me establish my main font style. 
• Which three colour colour scheme would suit a magazine aimed at females aged 15-25? This will help me establish an appropriate colour scheme.
• Which articles would be appropriate? The most popular choice will be taken in to consideration for my main article.
• What type of images would you like to see inside? This will help me to take appropriate images for the contents and main article.
• What type of image would you like to see of the female artist on the front cover? This will help me take an appropriate picture for my front cover.
