So how can we know if the world/universe and the laws of physics themselves are ‘real’ and not just our brain experiencing these models as reality?

Because of mathematics. The structure of mathematics is so unrelenting that not even God can change it. On the other hand, we cannot experience our actual mathematical models of physical reality.

Are abstract entities Real scientifically speaking ( rationally)?

I don't think that platonism works. I think that only implementations can be real. We cannot observe the actual implementation of the universe however, but we can show that we can describe it as transitions between states of information. Our models are formed about information.

Is mathematics an abstract entity ( independent of what it so accurately describes or predicts about the physical world)?

Mathematics is the domain of all formal languages. It is Hesse's "Glasperlenspiel". Mathematical objects exist in the same way as the Mandelbrot fractal: by picking a set of rules you can derive them, but they don't have an existence independently of the rules.

So your position is that abstract entities are less real than say, physical objects?

Physical objects are encodings that we discover over observable patterns of information. Something real is generating the patterns. This underlying reality may be mathematical in nature, but the mathematical objects we think about construe a purely virtual domain.

So therefore you believe mathematics is real and the world/universe is unreal as this is just the model in our mind? Mathematics generates the pattern i.e the universe

No, mathematics is eerily accurate at DESCRIBING what is real. It is only one of many ( the most powerful we know of) abstract entities that that- depending on what level of emergence you refer to... is real. This is true for only part of mathematics btw.

I think that everything that exists relative to us has to be computational in nature. Computation is constructive mathematics, which happens to be the correct part of math.
