A what seems to be red hair and uses dual guns girl
A guy who uses blue glowing sword
A chick who uses bow and seems to be in a temple clothes
and lastly a girl whos in something that looks like a karate suit

all seem to be in a action manga/anime saw them in a game and would like identification, seems to be interesting characters xD

The First one MAY be Gunslinger Girl, I know there are a couple brown/red haired ones, at any rate. I'm not sure though, as your description is kinda vauge.

________________

Name of the game or some SShots from it would make it a lot easier to help you.

1) I thought of Levy from Black Lagoon.

3) Kagome/Kikyo from Inuyasha maybe? (What kind of temple clothes? Japanese temple or made-up temple?)

there are a few manga/anime with a miko (priestess). the first one that comes to mind is inuyasha cant remember the others..........

he means all of these characters are in one manga/anime.

A picture or a more detailed description of the characters would help. Also maybe a summary of the story these characters were in. If we know what anime/manga they're from we'll know who the characters are.

Feed your head.

no all in a different manga/anime
will try to post pics if not still try to help xD
and they all seem to use techniques with names or something like that

Sounds like a dojin game and not a manga.

the closest thing I can think of is Night Wizard The Animation
it as a red-head gun-user girl,
a sword-user boy
a crossbow-user miko
and another one
