No, they're all just on X-BOX and X-BOX 360 (and HALO 1 and 2 are also on PC)
No, the Halo games are only made for Xbox/Xbox 360

Not to be a grammar Nazi or anything, but I had a little bit of trouble understanding what you were trying to ask. If you were asking if any Halo games have also been made the PlayStation 3, then no. Halo is an Xbox 360 exclusive franchise.
No it will not
no there are no halo games for the Wii. halo games are only on the XBox (halo 1-3, wars, odst, and reach) and PC (halo 1 and 2).
Yes a person can play playstation games on a playstation 2 .i have a playstation 2 and i can play ps 1 games on it.
Technically games still come out for the PlayStation 2, mostly sports games. However, the reason for the lack of new releases for the PlayStation 2 is because the PlayStation 3 is the newer and better console that replaced it.
No the Halo series is exclusive to Microsoft (the Xbox, Xbox 360 and PC)
No. PlayStation 2 games are not backwards-compatible with the original PlayStation.
No. PlayStation 3 games are not backwards-compatible with the PlayStation 2.
Currently no, but I'm a big halo fan so keep your hopes up.
No PlayStation 3 games do NOT work on the PlayStation 2 system.
