You're looking at it the right way already. As a lifestyle, rather than a diet. You're 17, so your metabolism is going to do a lot of the work. Don't worry too much about your diet aside from keeping...
Nothing wrong with a little bit of a difference in opinion. I would suggest a "mini-cut" followed by a lean bulk. I've had various stops in training and what I've found most effective is taking 2 to...
Cut. You obviously want to gain weight so that you look good. Therefore, get rid of the fat and then work with a clean bulk. I'm confused by how you could be confused by the fact that you're c.20-25%...
Just work out obliques! I've had the same issue. I used to Powerlift and neglected core since I would always use a belt. Get onto weighted obliques/core and you'll notice the physique look thicker.

Definitely wouldn't worry too much about your macro nutrients. You should focus more so on just getting yourself onto a healthy deficit (-200kcal) and bump up the cardio. It really isn't too...

Do your best to follow a routine which incorporates full body workouts. You'll notice gains relatively soon. Also recommend a light surplus on your diet (100-200kcal). At 150lb, it just looks like...
Definitely cut. You're carrying a lot of BodyFat to the extent that the shape of your physique has been compromised. Not sure if it's because your body is underdeveloped (I'm assuming it's not), but...
Physique looks fluffy. Don't be afraid to play with sustainable deficits. Judging by your bulk, you've been at a surplus of 500kcal? Wouldn't be harmful to try a deficit of 300kcal for 4 weeks whilst...
