1 - there are 264 types of monkey in the world so I won't list them all, just say Google I love you as always.

Or they could be listed by family:
New World monkeys
Family Cebidae: marmosets, tamarins, capuchins and squirrel monkeys (56 species)
Family Aotidae: night monkeys, owl monkeys, douroucoulis (8 species)
Family Pitheciidae: titis, sakis and uakaris (41 species)
Family Atelidae: howler, spider and woolly monkeys (24 species)
Old World monkeys (135 species)
Superfamily Hominoidea: apes
Family Hylobatidae: gibbons ("lesser apes") (13 species)
Family Hominidae: great apes including humans (7 species)
2 - the original 'monkey' we evolved from is often calked Proconsul. It was the first group of primates to show both monkey and primate characteristics. The species ranged in size from roughly the size of a gibbon to the size of a gorilla. They were arboreal but their teeth inparticular showed a change in their dietary habits. (I didn't need google for this one).
