Yes, they are all me to everyone except me. It would make no difference to me whether I commit suicide with or without exact copies of myself in existence. They will all lead happy lives being me, but I’ll be dead. My wife (if I still had one) wouldn’t mind, she’d have 10 versions of me to nag. 
I posed a similar question on these boards 18 years ago here. It doesn’t get interesting until about mid-way through the thread. My beliefs remain essentially the same now as then.
