need to run a method on entities every 5 seconds

but this is expected for example in an entity the time may be almost giving 5 seconds while in another the time is still at 2 seconds because it restarted

Don't expect us to write/design your mod for you.

 

But the simplest way is to add some code to your entity's tick() method and then check the ticks

@Override 
public void tick() {
        super.tick();
        if (!this.level.isClientSide && this.tickCount % 100 == 0) { // 100 ticks = 20 * 5 = 5 seconds
           // do stuff
        }
}

You can use LivingTickEvent if it is not your entity.

 

Or you can create your own tick/cooldown counter for your entity.

e.g. look at "chargeTime" in the GhastShootFireballGoal for a vanilla example of a cooldown.

There are many other examples in vanilla of varying complications, e.g. animal breeding, villager trading, etc.

 

Finally, you can look on github at the source code for a mod that does something similar to what you are trying to do.
