I get my share of spam -- most of it goes into the spam folder where it belongs.
Which spam folder - the one in your local mail client or the one on Yahoo's service?
If the former then your Yahoo service isn't doing its job.
During the past months I found a few spams disguised with the name and email address of former business clients and today the name and email address of a close friend in my inbox.

are any of my Mac's responsible for this?
Doubtful. While there are a few trojans around that will harvest address books and such, they're rather rare. And your anti-virus would have caught them.
Or, are spammers hacking into my friend and clients email devices to cause this disturbing disruption?
More likely, especially if they're using Android or Windows.
Or what else could be causing this? Is it something I should be concerned with?
Most likely - you or your friend's email account on the mail service (Yahoo in your case) was broken into and harvested. Services such as Yahoo's are under attack 24/7. Change your passwords.
OTGH, it's possible your conclusions as to the origins of the emails are incorrect. Them spammers is getting awfully good at forging things these days. Can't tell without seeing 'em tho, including complete headers.
