A single out is enough to get a save. To get a save a pitcher has to record the game ending out, and has to have entered with a lead of 3 runs or fewer, or with the tying run at the plate or on deck. If a pitcher throws the game's final 3 innings he can get the save regardless of how big a lead his team had when he entered.
There is no set amount of batters a pitcher must face to be awarded a save.
MLB Rule 10.19 specifies the rules for awarding a pitcher a save:
1) The pitcher must be the final pitcher used by the winning team.
2) The pitcher cannot be the winning pitcher.
3) The pitcher must record at least one out.
4) One of the following three conditions must apply:
4A) The pitcher enters the game with his team ahead by three runs or less and pitches at least one inning.
4B) The pitcher enters the game with his team ahead and the potential tying run is either on base or one of the two batters he faces.
4C) The pitcher pitches at least three innings.
Examples:
1) A pitcher enters the game with two out in the ninth inning, his team is ahead 8-3, and the bases are loaded.
If the pitcher records the final out, he is credited with a save. Looking at the rules above, he would be the final pitcher used by the winning team, he would not be the winning pitcher, he would have recorded at least one out, and he would have entered the game with the potential tying run being one of the first two batters he faced.
2) A pitcher enters the game with two out in the ninth inning, his team is ahead 9-3, and the bases are loaded.
If the pitcher records the final out, he is NOT credited with a save. Looking at the rules above, he would be the final pitcher used by the winning team, he would not be the winning pitcher, he would have recorded at least one out, BUT he would have entered the game with the potential tying run not being one of the first two batters he faced.
3) A pitcher enters the game to start the sixth inning with his team ahead 17-0. He pitches all four innings (sixth through ninth) and his team wins 18-1.
The pitcher is credited with a save. He was the final pitcher used by the winning team, he wasn't the winning pitcher, he recorded at least one out, and he pitched at least three innings.

No more than one save may be credited in each game. "
Yes, the pitcher who pitched the bottom of the previous inning would get the win and if a new pitcher is used in the bottom of the next inning and holds the lead, he would get the save.
If the relief pitcher pitches 3 innings, and completes the game, and never gave up the lead, he would get a save.
On August 2, 1980, Yankees pitcher Rudy May defeated the Milwaukee Brewers. He pitched six innings and Rich "Goose" Gossage pitched the last three innings for the save.
No once the game is tied, the winning and losing pitchers will be determined at that time. The winning pitcher will be the pitcher who pitched the last out of the half inning before his team took the lead for good, and the losing pitcher will be the pitcher who allowed the winning run on base

If pitchers' team is ahead when he leaves the game (all runners left on base that score, are charged to the pitcher that left them on base), he gets the win. The pitcher must pitch at least 5 innings in a game over 6 innings to get the win. If it is a tie game and the relieving pitcher's team wins, relieving pitcher gets the win. Otherwise he is charged with the loss. If the relieving pitcher's team is winning when he enters as a pitcher and then loses the game, the relieving pitcher is charged with a loss. If the relieving pitcher's team is winning when he enters the game as a pitcher and wins, the relieving pitcher is given a Save.
