Yes, they can fit.
DS/DS Lite Slot-1 games are exactly the same as DSi Slot-1 games, but Gameboy Advance (GBA) games are not supported by the console.
Important:
Any Nintendo DS game which requires an addon that uses the GBA slot, is not supported on the Nintendo DSi (eg. DS Lite internet browser or Guitar Hero: On Tour)
Note:
Because of the above reason, do not sell your Nintendo DS Lite if you intend to play Guitar Hero On Tour. :)
The DS lite and DSi are completely different pieces of hardware. You would have to buy a DSi, you can not turn a DS lite into a DSi
DSi Ware games and other downloadable content The Nintendo DSi Shop is specific to the region for which the system was manufactured. For example, a Japanese system can download DSi Ware games and other software only from the Nintendo DSi Shop for the Japanese region, regardless of where the system is being played. Nintendo DSi exclusive game cards Nintendo DSi game cards that are only compatible with Nintendo DSi and Nintendo DSi XL (and not Nintendo DS or Nintendo DS Lite) are region locked. This means game cards manufactured for the U.S. market would not work in a system made for another country. Nintendo DS / Nintendo DS Lite game cards Older Nintendo DS and DS Lite software is region-free, so you can play most of that software on a Nintendo DSi and Nintendo DSi XL from any region. It's possible, however, that future Nintendo DS software will incorporate region encoding. In these instances, these games would not work in a system made for another country.

Most games, I believe. But, The Guitar HeroTM games do NOT fit the DSi.
Yes, the Nintendo DS lite can play DSi games
If you mean simply trading one system for the other, then no, you cannot. The Nintendo DSi is worth about $150 while the DS Lite is worth about $110. You can, however, trade in the Nintendo DS Lite and cash for the Nintendo DSi. If you choose that method, you will need about $40 or so more to cover the cost. You can also choose to trade in your Nintendo DS Lite plus a game or two for the Nintendo DSi.
no, you can't download game to a Nintendo DS lite, it only works with a Nintendo DSi or a DSi XL

The DS lite and DSi are completely different pieces of hardware. You would have to buy a DSi, you can not turn a DS lite into a DSi

Only in the original Nintendo DS and the Nintendo DS Lite. DSi, DSi XL and 3DS do not have a slot to put GBA games into.
On the Original Nintendo DS, and Nintendo DS lite, you can play Game Boy and Game Boy Advance games. But on the Nintendo DSi and Nintendo DSi XL, there is no Game Boy or Game Boy Advance slot.
