I kindly ask your help on my program, as it doesn't work how it should:
I used 4 buttons on 4 digital inputs and one relay on output.
I have 4 sequences to trigger, each sequence triggered by one button.
The sequence must be triggered only when one button of four is pressed.
1: button1 = 15 pulses of 4000 ms each with 4000 ms pause after each pulse.
2: button2 = 5 pulses of 16000 ms with 10000 ms pause after each pulse.
3: button3 = 3 pulses of 32000 ms with 12000 ms pause after each pulse.
4: button4 = one pulse of 120000 ms.
I attached the code if someone is interessed to help.
Inline and formated properly. Please do that yourself next time. See How to use the forum.

And there is an important piece missing in you post. What is actually happening? "Does not work" isn't an answer
Alright, scanned though the code, couple or remarks / questions.
Why is everything in setup()?
Why are you programming backwards? You first try to do the sequence and while doing that you constantly read the button. Don't you want to read the button and based on that start (or not start) a sequence?
What should happen is a sequence is running and a button is pressed? Remember, the Arduino can only do nothing (but wait) while in a delay().
Thank You for your answer, I'll take care on the next post with formatting.
At first question: I put all the code in setup() because I thought that I need to run only once the sequence.
Second, I think that is another mistake of mine, I tried to use external pull up resistors, then pull down, then internal and I messed up.
While a sequence is triggered and another button is pressed, that button should be ignored.
What results I got until now: the relay module starts all the sequences, one after another, even if no button is pressed.

Thank you!

But you want to constantly check the button don't you? So all the sequencing should go in loop(). Only the setup of the pins (what's in de name) should go in setup()

Using the internal pull ups is great! Only you need to act on a button press. Not start a sequence and then check to see if the button is pressed. that's just backwards

Alright, easiest form

Yep, because you do stuff without checking the button Start by correcting that. And a small tip, just go back to one button. And I would just start over instead of editing. I think the current code will work confusing instead of helping you. So start over and try to do it for one button. So check the button (in loop) and only do a sequence when the button is pressed.
And a final question, are you planning to do more with the Arduino after you finish this sequence thing?
Wanting to do more with Arduino and baby steps are both very very good. But what I meant was, after you make this sequence, do you want THIS Arduino to do more besides the sequence?

This board will stay at least 5 years from now on with this code if not more...
And that is what I'm after Do you want this Arduino, while it is used to sequence lights, to do anything besides that? For example sequencing lights and playing a sound or sequencing lights and moving a servo?

Well, I think I will use a 16x2 LCD in 4 bit mode or a Nokia 5110 compatible LCD to show on the display the name of the current sequence and also a NTC sensor on analog INPUT to read temperatures from the room
Alright, so you want to do more then just a sequence. Then delay() is going to give you trouble A delay() does exactly that, it delays. And in that time NOTHING can happen. But, that we can work on after a working sketch with one button and delay()'s
