Undated but probably early 1988 following up on the large release of Dragons in December 1987's White Dwarf 96
Undated but probably February 1988 based on the contents.
Probably March 1988 based on the contents, and that the March Flyer only has fantasy releases. The Iron Claw Space Dwarfs don't appear until White Dwarf 100, but are Squats by then.
