i took some photos the other day using these settings

f/5.6 70mm 1/160sec ISO 200

I shot slightly under exposed due to shooting directly into the sunset and so i can recover the shadows in lightroom

but when i increased the shadows i noticed a lot of grain even though i only shot at ISO 200

Is it normal for it to be so grainy from the sony at those settings?

See examples below including histogram

Without EXIF, I can't know for sure, but ISO 200 + 4EV ~= ISO 6400 in terms of dynamic range. So yes.

Even on modern sensors, there's just limits to how much you can do without bracketing and converting dead black to something not-black takes effort. It's a multiple choice test where everyone mid-bubbles 3 Scantron questions. If it's out of 100, you can work with it. If everyone fails and suddenly the curve is out of 10...

And you took the left *tenth* of your histogram and made it into the left half.
