For each wallet you want to query the balance of, you will need to sync the blockchain. You can batch-process a number of wallets at the same time though, as you can add multiple wallets to PeerGroup.
Bitcoinj does not "download" the blockchain, at least it doesn't keep enough information to query balances (UTXOs).
