Permissible and Impermissible employment

Q: I am a truck driver, doing deliveries and pickups mostly all day. Today I was asked to pick a load from a brewery, which is alcohol. I asked the management to change it because I am a Muslim and not allowed to deal with alcohol. Its been two hours and I am sitting in my truck waiting for the decision to be made by management, which can be mean that I could be fired or forced to go home. Kindly let me know if I am allowed to haul alcohol or not, particularly in my case. 

Q: Can I give an entry test of an architecture university that might require to draw a face. And, can I practice for doing that beforehand. The university would also teach sculpture, art, etc. in the first year and I might be (or might definitely) be required to draw/sculpt faces and other things, etc. What is the ruling on this?

Q: I am an enginneer from Pakistan and I am working in a private company which is the offshore company of another Company in USA, so our office is controlled by USA company. That USA company makes electronic solutions including medical, residential commercial, military and a lot of other solutions. I am currently working on medical solutions but my concern is that the company also provides solutions to military. Should I be concerned about that or not? Is it halaal to work for this company?

Q: I am a product designer. I got an offer from a company. The new company buys good from China, modify the logo, colour, etc. and sell it in the European market. Among the things they buy mostly, are speakers, mobile phone accessories, and also musical instruments that include a guitar, or a drumkit.

My job is to suggest a colour and finish to the goods if required. Apart from that, the core business of the company is - it manufactures audio speakers (its own) and also synthesizers, guitar distortion units, and mixers. However I will not have anything to do with the core business department. My department is only concerned with sourcing goods from China, modifying it a little if required and selling it. Kindly give me your opinion if it is halaal or haraam.
