Grapple, Disarm, & Trip

[DMFTodd]

Grapple, Disarm & Trip are all "melee attacks".

If I'm a 9th level fighter, with attacks of 9/4, I can make multiple grapples a round right? I could start a grapple, if it fails start another one. Or I could start a grapple, it succeeds, go for a pin.

Can I mix and match these melee attacks? Can I, try for a disarm, it succeeds, so I then trip the opponent? Or can I trip and then make a normal attack?

If I'm a 20th level fighter (20/15/10/5) could I disarm, trip, melee, grapple an opponent?

Monks with Expert Tactician love to stun their opponent, followed by an Improved Trip, Disarm with the trip attack and a grapple when he's on the floor...

All with one attack.
