I guess that makes number 2 the Ethiopian mountain adder Bitis parviocula then.
I don't know the antelope.
Correct about the adder.
You also illuminated a detail about the missing animal that hasn't yet been picked up on...

Alright, may be time for some hints as this has stagnated.
DesertRhino did in fact get three in his first post.
The remaining ones include a species that as recently as 1995 was known from only three specimens.
Not likely to be confused for a duiker but a speaker of German may confuse it with an ibex!
1. Lungfish (South American?)
2. Javan Pond Heron
3. Grizzly Bear
4. Major Mitchell's Cockatoo
5. Tonkean Macaque
6. Honduran Milk Snake
1. African lungfish
2. Boat-billed Heron
3. Francois Langur
4. Scarlet Macaw
5. Moor Macaque
6. Bismark Pythoin
The first picture is indeed an African lungfish at Colchester Zoo. Numbers 4 and 5 are both also close.
That makes it a steenbok, then.
