I'm afraid they're not quite correct
1. I don't want you to feel left out (thereīs no need for "to be" -in fact you never put 2 infinitives like this together with "to")
2. You have a few options here:
We are running out of time
We are running late (we donīt add "on time" as it's unnecessary and does not sound natural)
We are running short on time
3. The objective of my speech was to bring them round to our point of view
The objective of my speech was to persuade them to see it our way.
Your version is too long and is actually incorrect. "to get around to something" means "to find the time to do something". e.g. I meant to call you last week but I just didn't get round to it.
Hope this helps
