"Each challenge has five challenge battles; challenge battle 1 to 4 has 12 fights and 5 has 15, including a boss fight against the challenge's unique character. Challenge battles can be done alongside Standard Battle without resetting progress. They can be done in any order, you don't need to complete a battle to work on another, although you still need to beat the matches in order."

No order is needed but you do need to complete them all.
