Please correct my sentences.(3)

1 - I have been invited to come here today, Why won't you want to let me in ?

2 - I would like to add one more condition in my contract.  Am I allowed to do that?

3 - I really admire your courage, but you need to be careful about being reckless.

4 - Don't ask me to admit guilt, I have said many times, I wasn't here at that time.

5 - I know that I made a big mistake, but don't you think that it's better to give me advise than to keep blaming me?
