Can anyone tell me why some of my messages show delivered and read and other ones don't? Any help would be greatly appreciated!

It's RCS messaging. It could be because you have RCS enabled but maybe others don't or don't have that feature because of their carrier.

Also, Google messages has options you can turn off in settings so senders can't tell whether you've read the message, or not.
