Each vs Split in Craps
When you use the phrase "Each" you're betting the same amount of money on two different numbers. E.g. "Can I have $1 'each' High-Low?"
You can split two different two numbers with an odd amount (like $5) with the phrase "Split". E.g. "Can I have a nickel split on the Aces-Ace Deuce?" Some casinos won't allow odd amounted splits ($5) because they're improper ($2.50 on each).

High - Low

You're not going to say anything special for these two. You just say "Can I have $1 each Aces - Ace Deuce?"
Seven - Eleven
What Are Some Common Three Number Multi-Bets in Craps?
There are a couple popular bets that include three numbers and they must be bet in multiples of three.
This is betting the 12, the Aces, and the Yo. Most people love the Yo and who doesn’t like the High and the Low, they are the two highest paid bets on the table.
Three Way Craps
The Three Way Craps bets the Aces, Ace Deuce, and the Twelve. It is more of a hedge bet. Whenever people bet the Pass Line on the Comeout Roll they lose when any of those three numbers are rolled so it's not a bad bet when you're deciding to hedge.
The Three Way Craps and Any Craps are similar because they both bet the same numbers but different in how the money is distributed. A Three way is betting each of the numbers individually so depending on which one rolls, the payment is different. The Any Craps is betting whether or not any of the three of will come and it pays the same regardless of which rolls.
