Yes, the spanners are adjustable.
Yes. Works fine with a dimmer switch.
What white trim with gimbel 20 watt LED 3000k or less fits this housing
Yes. I suggest soft white for interior. I love them
Yes! The lights have built-in clips to attach to the suspended ceiling grid. The housing can be lowered to be flush with the ceiling tiles. Once the trim is installed, it's a really nice look, as I did this exact thing.
Yes. Description states "IC-rated for direct insulation contact."
If you have enough room to install it, it will work well depending on the degree of slope. If the slope is acute, a sconce might be a better choice.The housings allow for insulation to touch then so insulation isn't a problem.
Yes they can BUT, you need to make sure that the LED bulbs in your fixtures are rated dimmable bulbs--they are more expensive though. I have 6 fixtures on 1 dimmer and they work fine. You also need to be aware of the maximum wattage your dimmer switch is rated for and then you can calculate how many of a particular bulb/fixture that dimmer can control.
As it says, there are 6 fixtures per package. Home Depot MAY sell them individually but you'll have to ask them.
