What is the old hole in the wall here? I do not think it is the ATM.

If this play is set in a prison, then the hole in the wall might be an escape tunnel or something similar - ie: you and I are escaping tonight.

I hope your eye is in. I hope your game is up. Because to tell you the truth, I'd love a run for my money just once.
Can you explain, rewrite those three sentences for me?

I hope your eye is in - Comes from shooting, where your eye is in once you have established the range and are regularly shooting bullseyes on a target.

I hope your game is up - That you are in good form and ready for anything.

Because to tell you the truth, I'd love a run for my money just once -Because I can assure you that just once I would like to succeed.

A: (Handing Richardan envelope) Here there’s a card here for you.
B: Who’s it from?
A: The Department of Social Welfare.
A: (Throwing it away) Ah that’s only my balls!

What does A mean when he says "Ah that´s only my balls!"?

He is being sarcastic. He is suggesting that the Department of Social Welfare have taken everything from him - "balls" is slang for "testicles".

If really helps if you give the basic theme of the plot for the play as that can affect idiomatic usage. I have given some suggestions above, but they may be wrong.
