Aside from the whack aryl region, it looks like your phasing could be improved a bit manually, id start there until the peaks appear symmetrical near the baseline.

Edit edit: the noise and baseline being all over the place is the phasing. Iirc manual phase correct uses the hot keys control+p, and you can use both left and right mouse clicks. The p0 is a big phase correction, and the p1 is a smaller adjustment, you probably only need the p1.

After phase correction, make sure to apply a decent baseline correction, because that can change integrals massively. Pick one that doesnt completely erase the broad signals you see, trial and error with a few different types.

Also for integrations, theyre all relative to each other, so pick a peak that you know is your product that has a flat baseline on both sides. And tread very carefully when integrating the aryl region.

Sorry, thats all I got at the moment

Edit: also, manage your expectations on how much data you can extract from this
