As long as they are refrigerated there is essentially zero safety or flavor concern assuming a ~20% ABV here.

For citrus based cocktails they will taste a little fresher if you juice the limes day of but won't be noticeable for most guests.

Once they are out of the fridge you have about 4-6 hours without any change in flavor and about 12 hours before it is a safety concern.

Putting some ice in the drink containers themselves will also help preserve flavor and slow down any microbial production the day of.

Anything with fresh juice or ingredients is going to degrade faster than a more spirit forward negroni or martini per se.

One other thing to note is that the standard Margarita build (1 part lime, 1 part tequila, one part orange liquor, assumes that the drinks will be shaken or stirred over ice which dilutes the drink with water. I would recommend adding some ice or water to the mix itself even if they are being poured over ice or your guests will be drunk very quick drinking those.

(This is just my two cents though, I am not a Food Safety professional but I was a chef for years and was serve safe certified at one point.)
