File transfer with queue

Good day! Is it possible to transfer multiple files at the same time using the get command ?
My problem is that I need to receive hundreds of small files in a short time, literally 10 bytes each.

And if you just do it with the get command, then the files are transferred one by one.

No, the scripting does not support parallel transfers.
But see Automating transfers or synchronization in parallel connections over SFTP/FTP protocol.
