You can really take this as far as you want. There are tons of books on African-Diaspora music all over the place. Tons of books of how these specific styles apply to the drum kit.
Timbale usually plays mambo bell, clave, cascara, and the abanico leading back into the one... There is no cascara sound on e-kit timbales. Just the drum.
Conga sounds on e-kit are very one dimensional. There are tons of specific rhythms, but you can't play correctly with sticks on e-pads. I would use them as a sound effect.
Surdo is more of a bass drum or dun dun type of sound. Played for samba/samba reggae, but again probably best as an effect.
Guiro is a very cool instrument, but there are actually 3 different sounds which make up the pattern. I think again you are limited electronically with this instrument. Played with salsa, merengue, "guiro", cumbia etc...
Agogo is another samba instrument.
These instruments are very commonly found throughout all music now, but they have very specific cultural and musical contexts and histories. Throwing all of them together (tabla included) on preset e-kit settings has always seemed really gimmicky and lame to me. I would suggest building a custom kit using the sounds which make sense to you for the music you are playing. Maybe throwing a timbale, or agogo on one of the cymbal pads makes sense. But I think it is a backwards approach to assume that you must use those sounds. If nothing else, it is a good start point for learning about some of the history of these percussion instruments.
