Thanks!

Can we say that the para is major in the nitration as there might be steric hinderance in ortho position?

Yes, I can agree with that. Sterics will play a small role in the balance of the two products.

i thought NaNO2 would give us azide N2+

It creates a species called a diazonium salt, and as she said in the video, it spontaneously breaks from the ring because N2 is a very entropically-favored gas, and then creates the vinylic carbocation.

Why does H30+ donate an OH group and not just an H?

That's a great question! If we think about it mechanistically, the positive carbocation on the benzene ring would be attracted to the partially negative oxygen over a positive hydrogen. It's the oxygen (and not the hydrogen) of H3O+ that should attack. Your professor will probably not require you to know the full mechanism for something like this, but you can at least think about how the opposite charges will attract.
