uW Translation Notes:

וְ⁠אֵ֣לֶּה שְׁמֹתָ֔⁠ם בְּ⁠חַצְרֵי⁠הֶ֖ם וּ⁠בְ⁠טִֽירֹתָ֑⁠ם שְׁנֵים־עָשָׂ֥ר נְשִׂיאִ֖ם לְ⁠אֻמֹּתָֽ⁠ם

(Some words not found in UHB: these they sons_of Yishmāˊ^ʼēl/(Ishmael) and=these names_of,[are]_their by,villages_of,their and,by,encampments_of,their two ten princes to,tribes_of,their )

The Hebrew words for settlements and camps overlap in meaning. Both refer to temporary or permanent places where people settled, surrounded by some sort of wall or fence. Also, many translations have “princes” here instead of “rulers,” but these Ishmaelite rulers were not actually sons of a king. See how you translated rulers in Genesis 17:20. Alternate translation: [who became the rulers of twelve tribes that were named after them, and each tribe lived in its own settlements and camps] or [Each of them became the ruler of a tribe that was named after him, and each tribe had its own villages and tent settlements]
