scored 232 (ls-77, qa-71, lr-84) in nmat will I get call from NMIMS mumbai or should apply for other colleges

nope man it doesnt seem possible unless cutoff is same as last time. Mostly people are saying overall cutoff to be 235

I scored 216 in NMAT, which campuses should I expect to get a call from?

it is based on your location as you will get tier 3 colleges

28,6,10=44.in cat, will my marks increase after scaling? and expected percentile?

Even if they do, its a 2-3 marks increase maximum. The lower the marks get more the number of people in that score. On 120 marks there are 5 people, you take it to 110 there are 20 odd people there. You're looking at 80-85%ile but IMO please prepare for XAT, there's more time and getting 95%ile is very easy if you know your stuff.
