Clutch ec 125

Watch the attached images for better understanding.
Hi, I got 2 questions. My first question is:
Does it really matter which way the iron and aluminium clutch disks go? I have assembled my engine and really don't feel like reinstalling them. Is it really important and how do you even tell the difference between the disks? Number 15 is iron and 25 is aluminium on the picture attached.
2. Now this one is really sad. Today I snapped one of the fingers on the clutch disk. There is in total 12 and now theres only 11. I know I should really buy a new one, but im short on money and energy. At this point im soon giving up. Do I REALLY need to? The clutch disks are still held by 11 fingers. Please be realistic, not worst possible scenario because I know I should get a new one. However theres literally a functioning gasgas engine without cylinder for 150 dollars in sweden. At that point its cheaper to buy a new engine
