For debuf purpose, change your code to:
userlist = {"user" : "password", "user2" : "password2", "user3" : "password3", "user4" : "password4", "user5" : "password5"}
and:
print ("User incorrect "+x)
and run the code.
You will see that the message is printed every time the input is not the username you check. The problem is your logic, you know the user is incorrect only once you have checked against every usernames in your list and that there was no match.
What you have to do:
loop in userlist
check for a match with input
if there was no match
user is inxorrect
There is a tool that allow you to see what your code is doing, its name is
debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is
debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
