After doing 5x5 for a while I can now lift my BW in squat but Im having trouble keeping my core tight and as a result find it difficult to keep y form.
You need to learn to keep your core tight, it's a basic skill of lifting so don't try to avoid it because you'll regret it later. Also, when you wear a belt you still need to use it, wearing it in itself doesn't give you core tightness which is a bit different from no belt but not hugely so you might not be able to use it well anyway

Any advice?
Once you have correct technique nailed down and feel like you need one, get one. But make sure it's one that is of uniform width all the way around and not a tapered one.
Not to any significant degree. Deadlifts would help a lot more. The idea is to add direct work for both the abs and lower back. Planks are great though, a real one-stop shop, and you can do them at home in your spare time.
Never had abs be the weak point on my squat unless I was using a lot of gear. More likely to be a technique issue IMO (see the video I posted about overarching). Especially likely since OP is a woman.
I'm also going to shout up and say no to the belt. Get a PT session and work on your form. Work on your core strength. I like TRX crunches and russian twists for core work, but whatever works for you. A nurse told me off once for using a knee support, with the reasoning that the muscles and tendons should be far stronger than a bit of neoprene and elastic, and to go see a physio. She was right.

Yes, I would agree with this. Squats work the abs extremely hard. If you're squatting correctly you won't have weak abs.
