Modern rat poisons are anticoagulants and kill by causing wounds to bleed uncontrollable. Unless the horse also receives wounds it should be fine and the rat poison will clear their system. However it would still be a good idea to get the horse to a vet.
The answer is not simple; the effect depends on: - type of the poison (chemical formula) - the quantity ingested - age - another illness - the first aid etc.

Rat poison is usually an anticoagulant that is it is a chemical that stops blood from coagulating. So yes it should finish off (kill) an iguana if it eats enough of it.
If the horse ingests enough yes.
Yes if it eats enough of it . It will kill humans if we ingested enough of it.
rat poisons prevent blood clotting and thinout membranes which causes internal bleeding and eventually death. usually after 2-3 days to prevent rats assosiating between the poison and the dying. should a human consume rat poison all he needs to do is get a lot of vitamin K which is the ingridient in blood clotting the poison disrupts and he'll be fine.
