"1 other" or "one other"?

It's used multiple times in the UI, in different lists, like: users in the dialogue, users in your project.

Example:

Tom, Bob, Linda, and 1 other.

Tom, Bob, Linda, and one other.

For all the other numbers we use numerals:

Tom, Bob, Linda, and 5 others.

Tom, Bob, Linda, and 20 others.

If we use numerals for numbers 2 and higher, should we spell one, or use the numeral 1?
