for the last 3 pictures: no 92, no. 99 and no. 104.

Thank you for any suggestions.
Is this the northern echo quiz, nanny? If so, lots have been asked and answered before - if you put northernecho in the red search box at the top of the screen, the other threads will come up. Hopefull you'll find your answers there!
