Just to confuse things, it depends in which context these are used. Each one may mean different things depending on the situation.
1. Could have.
This means that something may or may not have happened, or may or may not happen. It is used when an event is uncertain. It can also be used to imply that an event had the potential to be much worse than it turned out to be.
"I haven't heard from my son in four days. He could have had an accident."
"The upcoming elections could have negative implications."
"Although I scratched my parents car, I could have crashed it."
2. Might have.
This is almost exactly the same as could have. In certain situations though it implies that a person is likely to do something.
"I might have a pizza later."
"I might go to the pub later."
3. May have.
This is the same as could have.
"I haven't heard from my son in four days. He may have had an accident."
"The upcoming elections may have negative implications."
"Although I scratched my parents car, I may have crashed it."
4. Must have.
This shows that something definitely has or definitely should occur.
"My car isn't where I left it. Someone must have stolen it."
"I haven't seen you in a long time, my friend. We must have a drink together."
"Simon has put on a lot of weight since I last saw him. He must have stopped exercising."
5. Should have.
This is used for stating an alternate but preferable choice to a one someone has made in the past. It can be used to state that something has not done what was expected. It can also be used to imply something should happen.
"Instead of spending all of his money. Mark should have saved it up."
"For some reason the robot continued to roll off the high platform. It should have stopped at the end."
"We have not spoken to each other for a long time. We should have a night out together."
6. Would have.
This is used for an alternative to something that has already happened.
"I would have been on time, but my bus was late."
"I would have had to hand my homework in on Tuesday, but my teacher was absent."
I hope that's helped you.
