Question

what are the two meanings of ich and es in german?

Answer 1

I = Ich
You = Du
He, she, it = Er, sie, es
We = Wir
You = Ihr
They = Sie

We use "he, she, it" in german like in english and wouldn´t never replace "he, she" with "it".

In english, I think, you would also say:
Wo ist unser Kind/Baby? Es spielt draussen.
Where´s our child/baby? It´s playing outside

Answer 2

Ich is I.
Es is "it", but in some cases it can also be "he" or "she", especially if the "es" is a child.

Answer 3

I and it
