Speaking to a girl's father with regards to nikaah

Q: My friend wants to marry. His mother is a Muslim but not religious and not practising (does not cover herself properly, no 5-time prayer, etc) and even has a boyfriend (she was divorced a while ago). My friend asked me how to approach a girl in university? Obviously, the proper way is through the parents, elders or imams, etc. Actually, I personally also need guidance on this matter. He says "since my mum is not religious, I cannot really approach the girl to speak and deliver my proposal as mum is not interested and would not be really helpful in this matter since she herself is involved in a haram relationship..."

Please, advise us on this topic. How to approach a girl whom you would like to propose? For example, if the girl is with several female friends at university, and they are near but do not hear the conversation between us, is this allowed? Or write something on a paper and give it to her in the presence of her friends (without writing any contact info except phone number just to hear her response, or write in the letter to give it back if she only sees him with friends, just letting her know about the intention to meet with her in front of her mahrams?) How can my friend eventually "catch" a girl at university in this case? I guess parents/elders/imaam will not go to university for this? 

How many kaffaarah will be given for breaking an oath multiple times

Q: If one breaks an oath multiple times about the same thing, e.g," By Allah, I will not commit this sin again," and when he breaks this oath, then without paying the kaffaraah, he takes this oath again, then breaks it once more, will the kaffaraah have to be given once, or for both times?

Similarly, if a person breaks an oath repeatedly about different matters, and without paying the Kaffaraah, makes oaths once again, does he have to pay the kaffaraah once for all matters?

Taking an animate picture out of necessity

Q: I heard that photos of animate objects are prohibited. Now I am preparing for a lawsuit against my landlord to get my rights back and the court needs evidence. I need a cleaning receipt to back my words but the receipt contains a human animate picture. This receipt is from a large cleaning company and can only be accessed online and I must take a screenshot (like photo). I heard under necessity haram things become permissible and to defend property is a necessity? Can I take the photo? If not I fear that my argument could be very weak and more injustice can be done to me as a tenant. 

Discharge during haidh

Q: I have two questions pertaining discharge during haidh.

1. I thought I had released discharge and went to check but when I wiped, it felt pretty dry and all i saw on the paper was slight dampness. the discharge i had prior to this was discoloured, so i believed im still in hayd. can i assume that the dampness i saw was normal dampness and that im still in hayd?

2. In another incident today, after i was done relieving myself and i washed myself, i wiped where my discharge comes out to check and i didnt really see proper discharge - all i saw on the paper i wiped with was dampness/wetness. can i assume that what i saw is just water from istinja?
