Frogs.
"Toads" are not, scientifically speaking, "a thing". Frogs and toads are together in the order Anura and whether a given animal is commonly called a "toad" or a "frog" has more to do with its appearance and habitat than any real valid taxonomic distinction. (The technical way of putting that is that toads are not a clade, but toads and frogs together are.)
Scientifically, a toad is just a frog that happens to have dry, leathery skin and/or live primarily on land.
There is no official name for a group of horned toads. They are typically just called a "group of horned toads [lizards]".
Best guess for Cane Toad Scientific name is Bufo marinus.
