Está bien.
Esta todo bien?
Está bastante bien.
¿Cómo estàs ustedes? is how you say "how are you doing everyone?" in spanish.
Hacer
A problem in English is that we use the progressive form for almost everything. It is not used very much in Spanish. So "doing that" is usually expressed in Spanish in the simple present tense. "Hago eso", or I do that. If you are doing that right now, you could use the progressive in Spanish, or "Yo estoy haciendo eso".
Doing good = haciendo bueno but this sounds terrible in Spanish. Generally speaking you should say "doing well" which is haciendo bien.
To say the table is right there in spanish its: "La mesa está allí"
Yo tenía razón would be the best way to say "I was right" in Spanish.

¿Qué haces?
