The third image corresponds to a member of the family Trichuridae.

The D-shaped eggs from images 1 and 2 resemble  oxyurid eggs, however they are  very large. I really not know what it can be.

dear Efrain

I think the blue egg belonges to trichura but I dont have any idea about others.regards

In my opinion, I support the idea of capillarid eggs, they were more frequently found in aquatic habitat rather than trichurids. Besides, a couple of genera of capillariinae were reported in otters (Capillaria, Eucoleus and Thominx), while Trichuris has been rarely found. 

For the first set of eggs, no idea, they are so big (bigger than the large-size egg, i.e. Fasciola). Probably not any helminth's egg.

Dear Efrain, first 2 images could be an Oxyuridae eggs, while the third one may be an egg Capillariidae eggs.Thanks

first two images could be Oxyurid eggs

third one is Capillariidae - resemble Trichosomoides

best regards

First two images may be Aelurostrongylus abstrusus,

third one is Capillaria aerophila

with all best wishes
