I think you would need to measure up the car seats you wanted to use, then check the dimensions. Car / booster seat widths can vary hugely and having three together can limit manoeuvrability for some like the Axis.
To be honest if I had 3 kids and was considering any of these, I would be looking at a 7 seater or similar like the X5, XC90, Discovery or Q7 to allow for the extra luggage space. If not, at least the next size up of X3 / Q5 which are very popular. I don't know what your budget is but you could get a second hand version of the bigger car with a couple of extra years or higher mileage for similar price to a newer version of the ones you've mentioned.
Sorry I can't answer the specific question on 3 kids in those models but hope that helps.
