I want to return first 5 items from array. How can I do this?

A more object oriented way would be to provide a range to the #[] method. For instance:
Say you want the first 3 items from an array.
numbers = [1,2,3,4,5,6]
numbers[0..2] # => [1,2,3]
Say you want the first x items from an array.
numbers[0..x-1]
The great thing about this method is if you ask for more items than the array has, it simply returns the entire array.
numbers[0..100] # => [1,2,3,4,5,6]
