Say you like a girl.

Is it dumb to ask questions about ways to find girls to that girl you like?

Yes

What do you mean?

I think he means that, is it dumb to ask the girl he likes for advice on getting girls.

Im thinking that he thinks he'll get some insight on what the girl likes or not by doing this.

It is the dumbest thing ever.
She'll take it as a sign of you not being romantically interested in her. Or, she might see it as you trying to make her jealous. You only ask friends those type of questions. So unbelievably tackless.

The only way I can see this approach succeeding is if you were using it as some sort of pick up line:
You: "So what do girls like most about a guy?"
Girl: "Hehe, um, his like smile and like he has to make me laugh. Hehehe"
You: "Do I make you laugh?" Smile.

But I can't see OP pulling off that kind of stunt. So stay away from asking her for love advice you nutter.

Girl: "Hehe, um, his like smile and like he has to make me laugh. Hehehe"
You: "Do I make you laugh?" Smile.
Girl: "Yeah you're pathetic LOL!"
You: "Fucking BITCH, baaaawwwwwwww!!"
Girl: "Hahahahahahahaha"
You: storms away, crying like a girl

No that doesn't work either...
