questions regarding EU20N

Hello,
I am just filling in the application for student finance 2020/21 for EU students and I have four questions.

1.) In my country, we use characters such as Š, Á, etc. This shows up for example in my name. In section 2-a it is written "Please complete this section with the details exactly as stated on your birth certificate or passport." Should I do the same in other places or replace these characters just like I had to in the UCAS application? (i.e Š -> S, Á -> A)

2.) Can I fill in the form using a computer or do I have to fill it in with a black pen?

3.) Is it alright to answer the question "Why were you there?" in section 3-b1 with an answer "I was living there" if I have moved there in my early childhood? I have no idea what else should I write in the box, but I am not sure whether my answer answers the question.

4.) In section 6-contact details, there is stated that "The contacts you give must live at different addresses". In my understanding, one of them can live at the same address as I do. Is that correct?
