Old Family Photos from Karlskrona, Sweden - Do You Recognize Anyone?

I inherited a mass of unidentified photos that had been kept in my great-grandmother's family album.  Of course, no one is identified, since the family knew the other members - but, more than 100 years later, I am at a loss.  My great grandmother was (American spelling) Hannah Olsen Johnson, possibly Hanna Ohlsson Johansson; she married Andrew Johnson (Anders or Andreas Johansson); they had two sons that I know of - my grandfather, Johan Waldo Johansson (Walter Johnson) and a son my Mother knew as Uncle Ben...
Just for the heck of it, I'm posting  five of my unidentified photos that were taken in Karlskrona, Sweden; some have a year embossed into the print.  If anyone who sees and recognizes any of the photos will contact me, via the Comments, I'll respond.  I really would like to know who these folks are!
