I have included some pictures of our plumeria plant. I've read the threads on sideway growth but as you can see in the picture this plant has literally grew straight up then shot out vertical. I want to repot it and position it in a different angle but am concerned about the trauma that I will cause it.
Looking at the plant I'm sure that it is not a single plant in the pot but four?
Or could it be two with one having three branches?
Please look at my photos and give me some pointers!
Thanks!!!!!

Definitely looks like two separate plants to me. I'm not too sure there is anything you can do to straighten it out other than cutting it off and rerooting it. Separating the plants wouldn't be too traumatizing, considering you can store them bare root over the winter. Plumeria are pretty resilient with these types of things. I personally, would cut the branch off and root it. I would also separate that trunk into its own pot. The worst that could happen is the branch doesn't root, and you have to wait for the new branches to form on the trunk. Back to waiting for blooms, but fixes your issue. The may start choking each other out in that pot together, anyway.

Thanks for quick response.....What would you say if I separated the two plants and let the vertical outlaw keep growing.....if it breaks off then I will re-pot it?

I meant horizontal outlaw....oops
