('brand' emphasises how new the car is. Maybe the owner had an old, second-hand car before, and this car is a new model)

Can we go for a ride in your new car?

A: @alucard_says. New car is a car that is new, different from your last car, but could have already been driven by someone. A brand new car is a recent model of car that has never been driven by anyone.

A: new brand = marca nueva
new = nuevo
brand new = estrenar

A: Brand new is assuring the person that it has never been used. New can mean that it is the first time the person has the object but the object itself has been used so when we want someone to know that the object is unused, we say it is brand new. We also use brand new to emphasise that we only just acquired something."This is my brand new car, so please don't slam the doors". (I just got this car, so please be careful with it).

A: Everything in your example is correct but in American English we would still probably say: "Really? What brand?"

As for me personally, I would say: "Really? What kind?" or "Really? What did you get?"

As you can see there are many ways to ask these types of questions. And often people will respond with both the brand and model without you having to specifically ask about them. Usually we start with a general question and then ask more specific questions if we want more information. I hope that helps.

A: The second one would be better for someone to understand that you want to know the brand, not where it was imported or etc.

A: 1 or 3

A: "What/which brand is your lost bag?"

A: "Could we see the brand logo on your watch" sounds more natural

"What is the brand of your watch" would be another way to learn what brand the watch is

A: You could say "it's a fast food company that has a lot branches / restaurants"

A: I'm not sure what you are trying to say in some parts. There are a few mistakes so here's a corrected version:

Since 2007, a brand name called Duke University and 100 university's principals campaigned to lower the legal age to drink to 18 years old.

A: It's necessary to make sure what the current brand consists of and how it should appear to others.

Or (if you don't mean appearance):

It's necessary to make sure what the current brand consists of and how it seems alongside others.

A: If this is a business situation, I would avoid using the word "stuff." You could use "that kind of [items, flyers, decisions, etc]." The point is to be as specific as possible about what "stuff" means.

A: "I don't care about famous brands" ←
ブランド名は特に気に入らない。（気にしてない)

The meaning of the above is rather different than
"I don't have a preference when it comes to brands."
ブランド名の中で特に好きなブランドはありません。
"I have a preference" = 「特に好きな～～がある」

You could use "prefer" instead, which makes it a little closer in meaning:
"I don't really prefer name brands."
"prefer" = 「～の方が好き」

A: I'm looking at (becoming) the managerial position of a brand campaign planner.
