Just One. And His angels, I suppose.
The bible does reference a “real reality” that we don’t see, and that there’s a “curtain” between our perception and that reality that God Himself can pull back when He so chooses.
Would that mean that Christ was, basically, God’s avatar? And the Holy Spirit a data processing routine that He uses to interact with us.
Wow, this could actually explain the mystery of the Holy Trinity, couldn’t it?
