The radius of the observable Universe is thought to be about 46x10^9 Light Years.
(And dark matter about which we know almost nothing, occupies perhaps 90% of it).
Our Milky Way Galaxy is about 100 000 Light Years across, and out nearest neighbour, the Andromeda Galaxy is about 2.5 million light years distant.
Answer2: My estimate of the diameter is about 320E24 meters.

The big bang theory states that all matter was once?
Far denser -- almost infinitely more dense -- than it is today. It is a mistake to say that the BB claims that our entire Universe was once the size of a proton. That statement only applies to what is now the VISIBLE universe -- that small sub-set of our Universe that we can now see. While this 93 billion light year diameter ball is pretty large, it is impossible to determine how much more of our Universe is out there, beyond our present ability to see -- the total amount could be infinite. Thus, instead of saying our entire Universe was much SMALLER than it is today, it is more correct to say it was much DENSER.
