The four digits can be used to produce infinitely many different numbers if repetition is permitted. Without repetition, there are 24 possible numbers. A lot more can be produced if the numbers are combined using binary oprations, fore example, 19 * 8/4 = 19*2 = 38.

(19 + 7) x 8 + 14 = 222
To get 5 using the numbers 19, 2, 6, and 3, you can subtract 6 from 19 to get 13, then subtract 3 from 13 to get 10, and finally subtract 2 from 10 to get 8. So, you cannot get 5 using these specific numbers.
Yes: (4*8+6)/2 = 19
