Arduino MultiTimer - arduino

Question

Newbie here.
I want to delay-off 5 sets of LEDs each set has 1 main push button to turn on the LED and 2 push buttons for increase or decrease its delay-off value.
Power On:
All LEDs off
All timers value min. value is 0
All timers are delay-off
function:
When T1 has pressed the delay off value increments by 10
When button (1) was pressed D1 will on and turns off after delay-off
the value was achieved.
Same functionality with other LEDs.
Consideration:
each sets are independent to each other which means if timer 1 has 1 sec delay-off timer 2 can be set to 3secs.

I search on many libraries, but I'm having difficulty on what to use.
I have my code, and I'm having the problem changing the timer value.
Here's my code--------------------------------------------------------------
#include <Arduino.h>
#include <Timer.h>
const int LED1 = 5;
const int LED2 = 11;
int btn = 6;
int addV = 7; //connect another LED to this pin (don't forget the resistor)
const unsigned long PERIOD1 = 1000; //one second
int unsigned long PERIODsum; //ten seconds
Timer t; //instantiate the timer object
void setup(void)
{
pinMode(LED1, OUTPUT);
pinMode(LED2, OUTPUT);
pinMode(btn, INPUT_PULLUP);
pinMode(addV, INPUT_PULLUP);
t.oscillate(LED1, PERIOD1, HIGH);
t.oscillate(LED2, PERIODsum, HIGH);
Serial.begin(9600);
}
int addVf(){
PERIODsum += 10;
return(PERIODsum);
}
void loop(void)
{
int addVon = digitalRead(addV);
if(!addVon){
addVf();
}
int btnS = digitalRead(btn);
if(!btnS){
t.update();
Serial.println("Loop Value: ");
Serial.println(PERIODsum);
}
}

Attached a tiny bit of code which works for 3 channels like you need.
Without any additional libraries needed.
The loop function calls funtions to check buttons and timer value and do then a 50ms delay.
What you have still to add is an press/realease function for start, increase and decrese button press. Else every loop (50ms) the buttons will detected as pressed. What mean the value of settime will increased all time.
