I do not understand this because I thought that 2 comes, before 3? Please explain to me how you came up with this answer? Have a Blessed Week.

Celes,
You're correct. 2 does come before 3.
First, let's take a look at what we get when we hit the reduce button for the question:
Inferences:
1. Since the fifth digit of the code must be more than the third, the fifth digit cannot be zero.
2. The second digit must be twice the first, and the only numbers available for the code are 1, 2, 3, 4, 5. Therefore, you can infer that one of the following two scenarios will arise:
Scenario A:
1 2 __ __ __
In scenario A, the 3RD slot can have either 0 OR 3, and the 5TH slot can have either 3 OR 4.
Scenario B:
2 4 __ __ __
In scenario A, the 3RD slot can have either 0 OR 1, and the 5TH slot can have either 1 OR 3.
-------------------------------------------------------
Okay, still with me?
Since 1 MUST be last, we know that we're going to have to go with scenario B.
This give us:
2, 4, __, __, 1
From this we can get our answer. Choice "A" is correct. The first digit MUST be 2.
If there is anything you're still having trouble with, let us know.

Would there be any other inferences or negations possible based on the information given?

Farley,
The Logic Games section is confusing at first. The only thing that makes it less confusing is practice.
That said, let us know what exactly you find confusing about this question, and we'll try to help.

I still don't understand how 2 is first

Never mind I got it!
You can also infer that since the value of the 3rd digit MUST be less than the value of the 5th, the 3rd digit MUST be 0 (since 1 is 5th).
This leaves only one slot unfilled. So 3 must go 4th.
