If they were popular Xbox Orignal games then most likely you can play them on your xbox 360.
most xbox 360 games can be played on XBOX LIVE. The most popular games are shooters such as Call of Duty or Assassins Creed. Hope this helps :)
Xbox live was on the original Xbox, meaning that there are several games which you can play online. Halo was the most popular game on the xbox. You can still play these games but noone will be playing them as the Xbox 360 has more and latest released games. Also, you cannot play Xbox 360 on the original Xbox, FACT!

The Halo games have long been the most popular game for the 360. Halo 3 is currently at the top.
Roblox
For Sure Every Game On XbOX Has Xbox Live
XBOX Live is not a game console. It's a online game service for the XBOX 360.
XBOX Live is not its own game system. XBOX Live is an online gaming and content delivery service that the XBOX 360 game system uses.
There is no "The Xbox Live", Xbox live is simply a pay-to-play game service where you can play Xbox 360 games online. It depends on the game if you can play it online or not, the game's box should on the back say if it can be played online.
I don't think that you can play an original Xbox game on an Xbox 360 live. But some games from the old xbox you can play on Xbox 360.
