I have a lot of succulents and agree with Ken! Especially no water during their normal dormant period in winter (Dec-Jan). Jade is one exception to this (as is Christmas "cactus"), blooming in winter months - so I water them then, but modestly.
Cacti can for sure take 6 hours (or more) or direct sun, but I've found that can be too much for some more sensitive succulents. Lots of bright but indirect light seems to work well also.
Though over-watering is likely your situation here, some people make the opposite mistake - thinking you should rarely or even never water them. Not true, especially in summer! Cacti and other succulents will thrive and bloom with summer watering on the order of twice a week - at least a cup for a quart-size pot, and similar. You can water to the point of flow-through, as long as they completely dry out in between, as Ken said.
Happy succulents!
