All the number ... is 186,400

"All the number ... is one hundred and eighty-six thousand four hundred." This number includes all of the men in the tribes that camped under the standard of Judah. Alternate translation: "The number of the men camped under the standard of Judah is 186,400" (See: rc://en/ta/man/translate/translate-numbers and rc://en/ta/man/translate/figs-explicit)

the camp of Judah

This refers to the three tribes that camp east of the tent of meeting: the tribes of Judah, Issachar, and Zebulun.

They will set out first

This means that when the Israelite camp moves, the camp of Judah will start walking out before the other tribes do. Alternate translation: "When travelling, the camp of Judah will start walking first" or "When the Israelites leave, those tribes will leave first" (See: rc://en/ta/man/translate/translate-ordinal and rc://en/ta/man/translate/figs-explicit)
