Is it possible to search to messages with the label 'Apps script queue' and give just these specific messages (not the whole thread) a new label?
When I use GmailApp.search('label:Apps script queue') I get the requested messages but when I assign a new label to these messages, all the other messages of the thread (on other places in the mailbox) will get the same label. And that is not what I want.

This code does not return an error while adding a label to a specific message in a thread and if you use thread list method you'll see that it is only placed in the specific messageID(treated separately). But once your UI(Gmail site) is in conversation mode, it will be viewable in both labels.
function searchMail(){
var threads = GmailApp.search("SOME SEARCH");
Logger.log(threads.length);
listLabel('me');
for (var i = 0; i < threads.length; i++) {
var messages = threads[i].getMessages();
Logger.log(messages.length);
for (var j = 0; j < messages.length; j++){
if (messages[j].isInInbox()){
Logger.log('me' + 'id msg: ' + messages[j].getId());
//Add label to the first reply
addLabel('me',messages[1].getId());
}
else{
Logger.log('me' + 'id msg: ' + messages[j].getId() +" not in inbox");
}
}
}
}
function addLabel(userId, messageId){
var resource = {addLabelIds: ["Label_6"]}
Gmail.Users.Messages.modify(resource, userId, messageId);
}

In Gmail, labels are applied to a thread and cannot be applied to a single email message of a thread.
You can however apply stars / colors to individual messages.
