Which one is better? A Nikon SB-24 Or A Nikon SB-28 I will be using each for a Nikon D40X?

I don't think either of those will be compatible with that Nikon.

Look on page 100 of your user manual.

I would consider Nikon SB 28 - Hot-shoe clip-on flash - 36 (m)

The new SB-28 AF Speedlight can be used with any Nikon SLR camera to open new avenues of expression in flash photography
The SB-28 is considerably smaller and lighter than previous Speedlights, weighing only 11.8 ounces, with dimensions of 2.7" x 5" x 3.6"
But the compact new Speedlight packs a punch with a GN of 118 at 35mm (feet)
Continuing Nikon's tradition of offering superior features and performance in its family of Speed lights
It has with its previous SB-26, SB-25 and SB-24 models
