you mean aramaic, right?
i don't know this, but i dare say someone on the christianity board could tell you.
the convention in certain circles of christianity is to render jesus' name as "yeshua", but frankly, this is usually only done to emphasise how it's really just "fulfilling judaism" and that, consequently, we should all convert - a notion which i hope i have already addressed in relation to the various questions about "jews for jesus". it was probably originally "yehoshua" (joshua) rather than "yeshua", though.
i'm not actually sure of the hebrew or aramaic version of "john" - i know it's "yahya" in arabic, though. "mary" is an anglicisation of the hebrew name "miriam".
simon = shim'on.
andrew and james i don't know.
philip is a greek name, so don't know.
bartholomew is apparently "bar-Talemai?" = "son of Talemai"
matthew is usually matityahu.
thomas, may be from the aramaic t'oma' = "twin".
judas iscariot probably means "judean assassin" if judas=judean and iscariot=sicarius, which is latin anyhoo.
thaddaeus i dunno either.
hope that helps.
b'shalom
