Don't triple post, you can edit your posts... Also, there are the First Apple, Second Apple, Third Apple, Fourth Apple, Fifth Apple, Ezio's Apple... so yeah, there are multiple Apples of Eden. Altaïr had the Second Apple, which was destroyed. You can also see that Altaïr's Apple in both AC1 and ACR has a different pattern on it than Ezio's Apple does in AC2, ACB and ACR. The rest you said doesn't make much sense and is speculation... there is only one Grand Temple.
