Bunlar türkçe nasıl denir/söylenir?

"How about you" also can be used as "ya sen nasılsın"? 

Many thanks.

How about "ne dersin"? How is this different from "ya sen"?

One other point with respect to "ya sen", I thought this was is reply to someone who asks you how you are, for example:

merhaba, nasılsın?

iyiyim, ya sen?

In the context of, for example, a group of friends sitting around a table discussing where to go for a meal, some friends would give their opinions whilst the rest are still deciding/thinking; then one friend say would say to them: "how about you? what´s your opinion?" In this scenario, do you still use ya sen/siz?

you could also say use sence if you guys are discussing opinions on a topic. Sence is like "in your opinion", so you could also go "Sence?"
