1. I'd love to introcuce them to you.

2. I'd love to introduce to you them.

3. I'd love to introduce the people to you.
4. I'd love to introduce to you the people.

5. I'd love to introduce the people who are standing over there to you.
6. I'd love to introduce to you the people who are standing over there.

(Which one is corrct? Is #2 correct or wrong? What about the other expressions?)

1 and 3 are perfect. 2 and 4 are not done.

5 is awkward.

6 will work if you turn "you" and "to" around: I'd love to introduce you to the people who are standing over there.
