There are no mobs expect for that tropicraft villagers , any advice ? :D I have custom spawner mod (i dont know if does matter)

Tropicraft uses a custom spawn system which is probably being broken, could you please link the custom spawner mod you spoke of? It's likely causing issues.

You shouldn't use 9minecraft for any mods you get, it is not a reputable site for finding mod downloads. Anyway, it is very likely that mod is breaking our custom spawn system for our mobs, yep.
