Settling one's debts

Q: I have a couple of debts I have to pay back. One is a non-interest loan via a friend. One is a previous student loan where the interest is extremely small. I took this loan out some years back when I didn’t know anything about riba. If I can get a loan (non-interest) from somewhere, is it permissible for me to invest this loan in something halaal in order to make money for myself so that I can pay off my debts first, before I get a job? For example, I am able to get a loan and invest in some business which would eventually provide some return. Assuming I still don’t have a job. Or, if I can get myself a job, although I have these debts, would I be able to save up and invest first before paying the debts off? Or can I save up and invest, while taking some of my savings and putting that towards the debts at the same time? What is the best course to follow and what out of the above us permissible? What way round is allowed?

Witnesses for nikaah

Q: When someone does nikaah at home. What is the procedure with witnesses? How many does the male need and how many the female? I have heard even without witnesses it is counted and it is only sunnat to have witnesses and to do khutbah. If someone has done nikkah without witnesses and khutbah is it counted?

Working for a company that is involved in making arms

Q: I am trying to find out for a friend the permissibility of working for a company that is mainly involved with making/creating arms and selling them to companies globally including countries that use them to kill Muslims. The companies main areas of business are Defence (80%) and remainder Space/Travel. He would be working in the IT division and would have no direct involvement with the defence areas of business. He has asked a few well known scholars who said it would be deemed permissible but wasn't able to get any elaboration/clarification as to how it was exactly permissible. The company is also involved in talks with creating an office in Tel Aviv.
