Car parking allotment issue

We have recently bought and completed registration of a flat in Bangalore (in a complex of more than 30 flats). The flat will be handed over to us in a couple of days. There were many minor issues with the consulting manager who has been taking care of our dealing with the builder. This one particular time I had a disagreement/argument with the guy for asking for security deposit of Rs.15000/-  owing to possible damages that could be caused during movement of inventories while doing interior work. Post this argument the manager has been behaving like he had some personal ill will towards me and my family wherever we visit the flat.

So a few days back we were allotted covered car parking for all of us. The parking spaces are all of different sizes (mostly big and a few were small). The bigger ones can actually park a car and a couple of bikes. The smaller ones have issues like a pillar right in front and one at the back which makes it hard for those who got such parking to take a reverse and exit out. I have been allotted on of the smaller parking slots.

These are my questions:

1. Is it legally right for the builder to randomly allot parking slots in no particular order.

2. Is it legally right for one house owner to receive parking slots of bigger size and the others of smaller size although all of us have paid the same amount. 

3. I own a 3 bedroom flat. Is it right for me to ask why 2 bedroom flats are provided with bigger car parking spaces than a 3 bedroom flat?

4. Is there any specific minimum size limit for a car parking slot?

5. Am I even right about questioning the random allotment of the parking spaces?

P.S - We had specifically paid Rs. 2,00,000/- for our car parking space. The agreement or sale deed does not have any mention of the size of the car parking size.
