Yeah, you can implement them like you could in anything - it varies per language but the lack of true higher order functions (anything except K) and lazy evaluation (all) means that there's not really an 'elegant' way for anything more than 1 term deep.
That's not to say that the 'combinators' in array languages are bad, they're very useful and a nice form of function composition that I wish most other languages had, but they're not really a true combinator in the lambda calculus sense. You can't pass the array language 'combinators' to other combinators.
