If sentences

[Nightmare85]

Hello,
I'm not very sure anymore about if-sentences.
Please tell which versions you would use in a conversation.
(No past - imagine you're staying in front of the guy or whatever.)

If you tell me your name I could help you.
If you told me your name I could help you.

If he stops driving that fast it would be safer for everyone.
If he stopped driving that fast it would be safer for everyone.

I wouldn't do this if I was you.
I wouldn't do this if I were you.

I didn't do this if I was you.
I didn't do this if I were you.

If I play tennis tomorrow, would you stop asking me?
If I played tennis tomorrow, would you stop asking me?

I have the bad feeling that all the 2nd versions are the only correct ones.
However, I would like to know your opinion as well and if all sentences are true.

Thank you!

P.S. It's not my first if-topic but it's a very complex topic for me.

Cheers!
