Answer 1

You can filter messages with attachments based on the subject that contains specific text like this

var subjectText = "your text";
var inboxMessages = await graphClient.Me
            .MailFolders["Inbox"]
            .Messages
            .Request()
            .Select("sender,subject")
            .Filter($"hasAttachments eq true and contains(subject,'{subjectText}')")
            .Top(5)
            .GetAsync();
