So I was out with my gay wingman and he introduced me to one of his friends who is 10 years older than me but she is a 10.

We were introduced and later she came back and we spoke again and later we all went out for drinks as a group of 6 or so.

As we were walking to another bar she said I was "dangerous" , and "charming". Then she gave me a nickname and used that for me for the rest of the night.

When we said goodnight she offered to go out for a coffee sometime soon cause we live close by.

Two questions

a. are those good iois?

b. should one kiss close after coffee?

She wants it, go give it to her

There is no specific or planned "time to kiss"

Just don't wait. If you two are alone, close to each other, simply keep great eye contact and lean in slowly; she'll meet you in the middle.
