They first appeared about 65 million years ago, yet some people believe it was 85 million years ago. ^_^
yes
The first primates seem to have emerged about 55 million years ago.

Primates first appeared during the late Cretaceous period, around 65 million years ago, but they became more diverse and prominent during the Paleocene epoch, approximately 66 to 56 million years ago. The earliest primates were small, tree-dwelling mammals. By the Eocene epoch, around 56 to 34 million years ago, primates had evolved into more recognizable forms, including early prosimians and anthropoids, setting the stage for the later evolution of modern primates.
That is debatable. Scientifically speaking, primates.
All chimpanzees are primates but not all primates are chimpanzees. Humans, for instance, are primates.
If you mean "Are all mammals primates?" then the answer is no. Primates are a type of mammal. All primates are mammals. Not all mammals are primates. For example, cats, dogs, bears, rodents... these are all mammals, but not primates.
What is an ape? We have been called the "naked ape", but is that a good description or just good publicity. More broadly, biologists classify the great apes and humans together as primates. We are primates and the first humans were therefore primates just as we are. Whether the first humans were the Adam and Eve of the Bible is a matter of faith.
Lemurs are considered to be among the most primitive members of the primate order, but they are not direct representatives of the first primates. They belong to the suborder Strepsirrhini, which diverged early in primate evolution, alongside other groups like lorises and galagos. While they retain some ancestral traits, modern lemurs have evolved separately for millions of years, making them distinct from the earliest primates. Thus, they provide insights into early primate characteristics but are not direct descendants of the first primates.
That is very interesting question, indeed. Your concern for the primates needs appreciation. The answer to this question is probably positive. Sickle cell anaemia is a natural selection in malaria endemic zone. The sickle cell trait patient is genetically resistant to malarial fever. So many primates suffer from malarial fever. From this finding you can say that sickle cell anaemia should be present in primates, who live in tropical countries.
No, dogs are not primates. Dogs belong to the mammalian family Canidae, while primates belong to the order Primates, which includes humans, apes, monkeys, and lemurs.
