Yogi Berra and Bill Dickey both had their number 8 jerseys retired by the Yankees.
Doug Flutie.
Todd Zeile. He played for the Yankees in 2003.
Steve shutt Yvan Cournoyer, whose number is among those retired by the Canadiens. (Steve Shutt wore #22) You're correct that Cournoyer's number was retired in his honor (as well as honoring Dickie Moore), but several Canadiens wore #12 after Cournoyer retired in 1979. Keith Acton wore it in the early 80's, as did Serge Boisvert. Mike Keane wore it in the early 90's before he was traded to Colorado with Patrick Roy.
Many Yankee players have worn #16, but none have worn it since Whitey Ford, in whose honor the team retired the number. It had previously been worn by hall-of-fame pitcher Herb Pennock, and by all-stars Monte Pearson and Joe Page.

Ace Bailey #6 retired by the Toronto Maple Leafs in 1934.
49ers Dwight Clark, whose jersey number 87 was retired by the San Francisco 49ers, made one of the most memorable catches in NFL history in the 1982 NFC Championship.
Nolan Ryan

That would be Johnny Bench.
There are quite a few well-respected former Red Sox players whose numbers were never retired, and baseball fans debate this endlessly. It is worth noting that the Red Sox have not retired many numbers over the years (thus far, it has only been seven former players). That said, Boggs spent 11 years in Boston before leaving to play for the Yankees. It is unclear whether that factored into the decision not to retire his number, but there seems to be little momentum for doing it at this point, even though in interviews, Boggs still says he wishes it would happen.
