One is pretty much grammatically correct but "still" should come before "wouldn't" not after. Perhaps a slightly more natural way to express the thought however is as follows: "Could it be that you don't want to speak to anyone here, even if they should happen to think the same way as you?"

You can say, "there's a person" (meaning "there is" a person) Or "There WAS a person" for a past-tense situation. For your sentence, "there's" OR "there is" would both be correct. "There were" - this would only be used for more than one person. I.e. "There were people at the bar that I didn't want to talk to. At the concert, there's a man I want to meet." I hope this helps =O)

I suppose,the 1st one is correct
