The first one is Haddie which featured in the Hotspur as a reprint and was originally in the Hornet. Haddie is a play on the nickname for haddock and as Harold Hadleyis a fisherman, it works fairly well. The artist is Giralt.
The final story is another D C Thomson's story with Joe Greer, who is The Fiery Man At Number 6. This was printed in the Victor but I can't swear if it was originally printed as a picture story in The Wizard or The Hornet. Phoenix will probably be along in a bit to tell you the original printing of this as a text story.
