Skappy's Pigman Puzzle Challenge

[Skappy]

I posted different puzzles throughout Townville (you get to it through the pink part of the main hub) and everyone who wants can come and try to solve them. But be warned, some of them are pretty difficult (especially 4 and 5), so do not expect to just come and quickly solve all of them. If any of them doesn't get solved for a while I will release additional hints.

There are also prizes for solving these puzzles, for each puzzle you solve you get:

-One enchanted tool (diamond or a bow) if you are among the first 3
-3 Iron Blocks if you are among the first 6
-64 pumpkin pie if you are among the first 12
-1 part of a 6 piece banner to show your accomplishment
That means the total prizepool contains 18 enchanted items, 108 Iron Blocks, over a doublechest of Pumpkin Pie and most importantly a bunch of glory!

This is where you can find the puzzles
(the town entrance (coordinates 180/-400) has a map telling you where every building is)
#1 The Labyrinth, downstairs in the Infocenter
#2 Safe Cracking, on the path to the Church
#3 Cartography, in the Library
#4 NUMBERS?!, next to the Infocenter
#5 The Hidden Shrine, at the town entrance
#6 ???, Has no position and can only be solved last

Rules/ Hints:
1.None of the puzzles requires you to break any blocks, so don't do it.
2. Do not rightclick noteblocks in the 1st puzzle or you won't be able to solve it.
3.You don't need to leave town to solve any puzzle except if you have specific coordinates leading you somewhere and even then they won't lead you far away from the town.
4.After solving a puzzle take your prize out of the chest and reset it again.
5.Do not help people with puzzles you already solved, but feel free to cooperate if you both didn't solve it yet.
6.I am not responsible for any ragequits caused by my puzzles

Congratulations to A_Bran_Muffin for being the first person to solve all 6 puzzles
and to That Nurd, Nii Chan, Snowyiu and Dax for solving some puzzles as well (I don't know who else did)
Also a thanks to everyone who tried but didn't succeed.

For those who still want to try their luck on the puzzles I'll release a few more hints, one for each puzzle:
1. I'm not trying to mislead you, the first 6 rooms are supposed to be easy to show you how the system works
2. The clues are hidden around the town, explore and try to find them.
3. You are searching for 5 (+2) things in total
4. It's Cryptography
5. Signs 1 and 4 are most important, but the other two are helpful too
6. The final Banner is supposed to be arranged like this:
