1. Samin
2. Draenei Paladin (male)
3. It basically comes down to just a random name that I liked the sound of. There was no relation to the race or class I picked.
4. Barely. It's no special name. It enables RP as it's not immersion-breaking. There was a shortly popular song whose artist was often wrongly named Samin but actually is called Samim. People asked if my name was related sometimes but as barely anyone remembers the song that doesn't really happen anymore (I like the song, but no relation)
5. Some details on question 3: Originally my Tiefling rogue in Neverwinter Nights 2. Which I came up from a variation of a random ferret familiar name in the same game (Tamin) and I liked the sound of the name so I stuck with it for much things afterward, especially RPGs because it doesn't break the immersion (for a wide spectrum of different settings too). Except for my main and my (now abondoned) first character, I named all my other numerous characters according to their race, class and/or general idea behind the character (for the immersion and all). Choosing a character name was often >50% of character creation time.
