Refusing a proposal due to concerns regarding the family's chastity and modesty

Q: Would it be wise to marry my first cousin whose sister got divorced but his family sent her back with her ex-husband (who actually orally gave her talaaq 3 times) knowing the ex-husband had given his sister divorce? She is now living with her ex-husband and his family. Thus frustrates me and her brother has asked for my proposal. 

Travelling safar distance

Q: If I intend to travel to a place which is more than 50 miles away (Place A), and intend to stay there for 20 days, I understand that I will not be a traveler and will not do qasr. However, after 20 days at Place A, if I travel to Place B which is 50 miles away from Place A, and intend on staying there for 5 days, will I do qasr in Place B?

Using a zikr counter

Q: Alhamdulillah I use a counter to make zikr. Generally I meet alot of people of different races, cultures, etc. All of them ask the same question. "What's the counter for?" Could you please advise me what to tell them. Something that'll be simple but InshaAllah a means of hidayaat for them. Something that'll attract them to Islam and create that love for Allah Ta'ala.
