Idiomatic expressions

[Chaine]

Could you guys help me with these idiomatic expressions, I have them in pictures and would like to have their idea in English. But the problem is that they have a meaning in Portuguese and I'm not sure if there is a meaning for them in English , but anyway , maybe some Brazilians might be able to help me. I am going to attach them . Thanks.

The second and fourth work as idiomtic English:
Walk the line- toe the line- behave as told to
Kick the bucket- die

The first one might be "(have) nothing up one's sleeve" - (have) no secret plan...
