Option 1: Stuff all five values into the same, non-global, non-repeating field with each value separated by a return. The list funciton can be very handy for appending values to a list in a field. When you set up your value list specifying this field, you'll get 5 different values. You can use a conditional value list to just refer to this field in a specific record or you can use a single record table related to your current table by the X operator. (Use the relationship to make it easier to edit values in this field.)
Option2: that standard alternative for repeating fields is a set of related records. I see no reaon why you can't just set up a 5 records in a related table for your 5 values And this too could be a case where you use a conditional value list to match to a specific set of records for the values or you can have just 5 records in the table.

Hmm...how does one implement a "conditional value list"?
See these links:
There's a lot of overlap between the first two links so you can read one and skim the other. The demo file gives you several examples of different conditional value lists so you can examine them to see how they are set up. If you are using FileMaker 12, you can open this demo file from your File menu to get a converted copy of the demo file that you can examine in FileMaker 12.
The last link discusses how to set up a chain of conditional value lists where the value selected in each conditional value list controls the values listed in the next value list.
