Something like this:

for (i = 0; i < 3; i++) {
/* create new TCP PCB structure */

pcb[i] = tcp_new();

/* bind to specified @port */

err = tcp_bind(pcb[i], IP_ADDR_ANY, port[i]);

/* we do not need any arguments to callback functions */

tcp_arg(pcb[i], NULL);

/* listen for connections */

pcb[i] = tcp_listen(pcb[i]);

/* specify callback to use for incoming connections */

tcp_accept(pcb[i], accept_callback);

}

i.e. Just create multiple pcbs, one for each port.
