The dealer has given two cards each to the four players who are betting. One of the dealer's two cards is face-up so all the players can see it (an Ace), and the other is face down.
(we'll refer to the players by poker chip colour: white, brown, blue and black)
Black gets an Ace and 2 which is worth either 13 or 3, and asks for a hit and gets a King (worth 10) which takes black to 13; black hits again, gets 16 and decides to stand.
Blue gets a King and Jack which are worth 20 together and of course chooses to stand. (Splitting a K and J may be possible in some games although it is unusual to split a 20 because it is such a high hand)
Brown gets a 10 and 4, and asks for a hit, gets 2 which takes brown to 16. Another hit and they get a 10, which means they are bust at 26 and the dealer takes the chips. Normally the cards would be taken away immediately with the bet.
White gets two 5s, so they double the bet and split the cards, the dealer gives them a 5 and a 7 for each. They ask for hits in both cases and get a 9 and 6, taking them to 21 and 16 respectively.
The dealer turns their card over and gets a 6, together with the Ace takes them to 17, and stands because the dealer must stand on 17. (In this case the dealer must stand on a "soft" 17). Results:
Black loses their chips because the dealer's 17 beats black's 16
Blue is paid the same amount of chips they bet because blue's 20 beats the dealer's 17
Brown has already lost their chips when they went bust before
White's 21 is paid at 2:1, which means that white receives double and a half the amount of chips white bet for one of the splits, however white loses the other half of chips bet on the 16 which is beaten by the dealer's 17. Most games do not pay 2:1 for a hand of 21 however.
