With adjustment there are a couple of things to watch out for
First as the previous post suggests - ask about accommodation. You'll have a very different experience at any of these universities if you have to find private accommodation between now and the start of the course and live outside halls.
Secondly (and most importantly) be VERY clear with these universities that you have not accepted their offers YET and are still exploring your options.
When adjustment opens and you hit the button on Track on the 13th you don't submit your application to your chosen university (like in Clearing) instead ANY university that you've spoken to that believe you've accepted an offer can go in and pick you up...so there is a risk if you've been speaking to multiple universities that one of them could misunderstand that you were asking for an offer and not accepting an offer and could go in and fish you out of adjustment.
Basically with all of them if they make you an offer thank them politely and explain that you will contact them on the 13th when you're in adjustment and would like them to formalise your place.
