What cocktails can I make from these ingredients: orange juice, triple sec, tequila, vodka, gin, soda water, Frangelico, Bailey's, and champagne?

Based on the ingredients you have on hand, you can create a delightful array of cocktails. Here are a few fantastic options that should meet your tastes wonderfully:

1. Orange Margarita: Combining lime juice (if you have some), triple sec, orange juice, and tequila, this cocktail is a vibrant twist on the traditional Margarita. With its refreshing blend of citrus flavors and a touch of sweetness from the triple sec, it gives you a delightful balance of sweet and sour.

2. Royal Orange Fizz: This elegant and celebratory drink mixes the citrus notes of fresh orange and gin, sweetened subtly with a touch of sugar, and topped off with champagne or prosecco. This cocktail offers a refined and bubbly experience, perfect for special occasions.

Though you might not have every exact ingredient for the other top-rated cocktails, you can experiment with the remaining ones to create something unique:

3. Vodka Sunrise: Usually requiring vodka, orange juice, grenadine, and a dash of lemon-lime soda, but you can substitute soda water for a bit of a different effervescent touch. This cocktail is bright, fruity, and cheery, ideal for a pleasant morning or a laid-back evening.

4. Orlando Quencher: Combining orange juice, lemon juice (if available), white rum (you can use vodka instead), and lemon-lime soda or soda water, this cocktail is zesty, bubbly, and perfect for quenching your thirst on a sunny day.

While the specific cocktails given don't precisely match all your ingredients, they can inspire some creative mixing. Feel free to adjust the proportions or add a splash of your favorite spirits, like Baileys or Frangelico, to craft a cocktail uniquely yours!
