They look like it, but they are actually in the accusative case because they are the direct objects being "had" (or not had). For masculine nouns that do not represent living beings (inanimate nouns), the accusative case looks exactly the same as the nominative dictionary form.

Why is "do not have" written as one word (nemaju)?

In Croatian, the word ne (not) is usually written separately from the verb. However, the verb imati (to have) is a special exception where ne merges with the verb. So, ne + imaju becomes nemaju.
