I’d like to use these in a fixture that currently is controlled by a dimmer switch. Is that okay?

One thing about having a dimmer, even at 100%, if it is a phase-cut dimmer, it can cause problems for digital electronics. Not sure how this bulb would respond, but all of the smart bulbs I've tried from any brand will buzz or flicker. So, if you have problems like that your best bets would be dumb LED bulbs that list compatibility with dimmer switches, or to replace the switch for a few bucks.

If you have say 4 bulbs on one circuit, can you program each bulb individually?

Yes you can. Each bulb can have it's own name or location regardless the circuit it is on. For instance, living room lamp, living room ceiling fan light,desk iight and you can group them together under one name like living room lights. You would still be able to turn on individually or as a group.

Can these or any kasa bulbs color cycle? Like just loop through the various colors?

I would like this feature too. Especially during during holiday events like Christmas to cycle from red, green, and white

Can these be used outdoors?

I am using outside but it is protecyby a fixture
