a515-51g-5504 - is there provision to add extra SSD/HDD?

I ordered in amazon with link description having model number: a515-51g-51j

I was delivered a515-51g-5504 model.

Questions:
1) which is a better model? Should I keep it or return and ask for exactly what I ordered?

2) Any setting to turn on keyboard backlight? I see the product comments in Amazon that the aspire series kB are backlit.

3) Is there provision to upgrade extra SSD/HDD? I don't want to open yet, let me know. I found in a comment that a515-51g-5504 has no space for add-on? Is that true?

4) in case a515-51g-5504 can be added with HDD, should I claim for free upgrade kit from Acer? Will that kit be delivered to another address other than my laptop delivered because I changed my address.

5) in case I need HDD upgrade kit, will I be able to get it India? I am moving to India next month.
