I have a question on how I can change the index of a array element, so that it doesn't come at the 7. position but at position 2 instead...
Is there a function to handle this?

The array can be left rotated by shifting its elements to a position prior to them which can be accomplished by looping through the array and perform the operation arr[j] = arr[j+1]. The first element of the array will be added to the last of rotated array.
Nothing is simpler:
array.insert(2, array.delete_at(7))
irb> a = [2,5,4,6]
=> [2, 5, 4, 6]
irb> a.insert(1,a.delete_at(3))
=> [2, 6, 5, 4]
