Orphans You bet on numbers 17, 34, 6, 1, 20, 14, 31, 9. This is called the Orphans arc on the Roulette board. You give five chips to the dealer, which are placed as follows: one straight on the number 1 and one split bet on every one of the numbers 6/9, 14/17, 17/ 20, 31/34.

17 chips (17:1) + 1 chips
17 + 1 - 5 = 13 chips
17
34 chips (17:1) + 2 chips
34 + 2 - 5 = 31 chips
Orphans bets
Neighbours Bet on number and neighbouring numbers on the right and on the left of this number. This bet is played with five chips. For example, "8 and the neighbors" means that the player places a bet on five consecutive numbers 11-30-8-23-10 (8 is in the middle).
The true payout is 35 + 1 - 5 = 31 chips.
Neighbours bets
Finals You bet on all of the numbers that have the same last number. For example, "final 5" means a bet on the numbers 5, 15, 25, 35. You need four chips, one straight bet on each number. If one of these numbers wins, you are paid regular Straight bet winning amount on that number.
So your profit will be 35 + 1 - 5 chips = 31 chips.
