I think they're all correct, but can mean slightly different things.

I agree with Red.

1. One has an appointment and one is happy.
2. Same as 1, but a bit wordy.
3. Same as 1.

4. This is a bit idiomatic. It would normally be used as a proposed appointment. It awaits confirmation. The future tense "I will be" can also be used.
