hacemos frio. In Spanish we don't say we are cold, we say we have cold. I like the difference, because cold is a temporary state-not who we ARE (excepting Canadians)
"Hace frio ahora" is how you would say it is cold now in Spanish.
You can say "Tengo frío" in Spanish to express that you are cold.
al frio
Esta resfriada
In Spanish, you do not say "Yo estoy frio". That literally means "I am cold", but it is not the normal way to express the sentiment. "Tengo frío" literally means "I have cold", but the translation would be "I am cold".
