Since I’m underage do I have to buy specific tickets or can I use the same tickets as adults?
Not sure, but I believe it's cheaper.
Do I have to go with adults or I can go alone even if I’m underage? (Both exhibition and concert)
Exhibition ticket I think has no difference. The concert one, they might ask for an ID to verify your age. Again, no info on the underage bit.
If I want to buy the «Pre-Order Full Graphic Live HAPPI » do I have to use a friend’s address in Japan or I can use the hotel address? And how long the delivery is?
Merch pre-order period is a month or so before the events, and they usually deliver it a week or so before that. it might be way too early to deliver it to your hotel. Might be better to piggy back on your friend's address, for peace of mind.
After receiving the ticket confirmation do I have to print the ticket?
Usually for the Accommodation Plans and Lottery Tickets - It's not yet a full fledged ticket until you exchange it in their claim booth. No worries, they email instructions on when and where to claim usually a week before; you print that for claiming.
Do a lot of staff at Magical Mirai can speak English (or Chinese)? Or we can get through the event without help and knowledge in Japanese?
Don't rely on it, but as I have said on other posts in reddit, you can survive and enjoy Japan in general. It will help out a lot if you study a bit what I call basic "tourist" Japanese (basic greetings, phrases, asking what, where, when; counting, time and money) Your Japanese may sound broken to them but remember the flipside that most Japanese also speak broken English. Besides, they'll warm up to you a bit faster if you impress them a bit!
Can we know the stands before the event or we will the have to wait the day of the event?
You mean the booths? yeah, someone usually posts them. Most Merch as well.
is there indications in front of the Intex Osaka building or we can easily see the gate for the exhibition?
You can streetview via googlemaps the INTEX area to orient yourself, but you can't miss its main entrance with the half-moon arch.
Or, you can follow the hordes of fans.
Is the concert in a whole different hall from the exhibition?
Yes. You might accidentally spoil yourself on the setlist if you happen to pass-by while they're rehearsing or the day concert is ongoing.
If I want to the exhibition everyday do I need to buy a new exhibition ticket everyday?
Yes, 500 yen, readily available in the exhibit hall entrance.
it’s my first time going to Japan and my first event outside of France. I’m very stressed and excited toward this event.
You remind me of myself when I was planning to attend my first Miku concert last 2017. First time as a solo traveler outside my country. Now, here I am, having the opportunity to use my solo trip experience to bring my family to enjoy a wonderful cherry blossom experience and attend my second Mirai last year.
Well, it's all thanks partly to the info that I got from the people here and its predecessor site.
and Ticket Lottery.
