Welcome to iMore. Press any text bubble to bring up the options bar. Tap "More". Then tap the small dots at the left of the text bubbles you want to delete. The dots turn blue. Then tap the trash can. Tapping the dot marks it for deletion. If you need more help, I'll be glad to show you screenshots of it. Just let me know.
