Receiving the normal price of an item when returning an item instead of the discounted price

Q: If a person sells a certain item and a discount was given to the customer and thereafter the customer wants to exchange the item or be refunded for it, will it be permissible to subtract the discount given (proportionally)? If the discount is not reversed will it be regarded as interest?

Selling a car as a loophole to acquire a loan

Q: I have a question regarding interest. I have a financial issue in my business. I need around 5 million to complete my running order. A friend of mine has an electronics business. He is selling his products at a higher price in easy monthly installments. As I told my problem to him, he bought a vehicle for 5 million pkr and sold me this vehicle for 7.5 million in six monthly installments. I sold this vehicle to the same owner at a lower price (4.99 million) and took money for completing my order. Is this haram in Islam? Because my friend is taking money against a product, not against money, and I'm paying him for a vehicle, not for money. If it is haraam, then what is the solution because I already used the money and invested in my business after selling the vehicle. 

Selling cigarettes

Q: I live with my grandparents and they have a shop which sell mostly biscuits & they also sell cigarattes! (According to some sholars in my country cigrattes are makrooh, while I have heard some Arab scholars say its haraam).

I want to be on the safe side so, as I live in their house my concern is I use electricity/internet to learn as I learn online! Will my online earning be halal if I pay them later on for electricity/internet I use?

Sales person processing an order with silhouettes of animals

Q: I work as a sales processed in a bed factory. My work is halasl but one aspect is concerning me:

I recieve requests from customers to make bed labels which the company has already designed & they contain silhouettes of 2 animals - the silhouettes vary in size, most contain a head 1 mm in height but some larger.

Before I send the request to the printing company, the customer previews the labels where the silhouettes can be clearly seen. Would I be sinning by sending the online versions & also sending the request to the printing company to print?
