Hook of echinococcus sp in picture 3
My thoughts precisely...echinococcus hooklet
The hooklet indicates an infection with tape worm, possibly cysticercus cellulosa or a hydatic cyst.
The thick, non nucleated, laminated cuticula is consistent with the supporting wall of a hydatic cyst since cysticercus cellulosa has a much thinner wall.

Alveolar echinococcosis. The hooklet, lamination of the cyst wall, and inflammation pattern are consistent with Echinococcus. The location in the lung would favor E. multilocularis.
Hooklet of Echinococcus...Lee
The hooklet looks so faint in the 3rd slide... maybe if you close the microscope's diaphragm a little you can have a better resolution of it. Sometimes less light is better to distinguish some parasitic elements.
