Stuck at a certain quiz club question

[in the kitputer :3]

the brother is asking "How many minutes after midnight did Andreas Kohlmann arrive at Hotel Letztes Jahr?" This one has really stumped me, because I can't find ANY mention of him in any of the documents I've picked up so far (I have picked up most of them). He is blocking my only path towards the center, so I can't just go around him ;-; Was wondering if anyone actually knows the answer to this one, or where I can find it. Thank uuuu

Have you opened any of the playing card doors yet?

You'll need to interact with a certain someone outside the hotel
1. Do you have a certain ticket? 2. How about solving the piano puzzle?

I did find the magician, and had a hunch I needed to give the cards to him. I assume the rose is behind the piano puzzle but I unfortunately have 0 idea how to solve at. I stared at it for like an hour and made no progress, a hint would be much appreciated

1. Look at the screen music, how many notes are there in each "block" ?
2. Remember that an empty block is also a number

Really unsure about the:

How long has the great Lorenzo walked on the earth. I have the manequin dates but it doesn't specify who is who?

In my case this answer came up in a movie poster room, check the hints for safes in them.
