Hola como estas, cual es tu nombre wey?

That means, "Hello! How are you (informal). What is your name?"

When I say informal, I mean like if you are talking to a friend or someone younger than you. When talking to an adult you would say Como esta. Como has an accent on the o and esta has an accent on the a.

Also, tu is an informal way of saying you. You would say Como esta usted when talking to someone formally.

El artículo más apropiado es el planeta es de nosotros

Buenas noches. that is the correct way to say it.
