Can this be connected to any speaker with a 3.5mm or 6.35mm socket?

You should be able to or if the device has a quarter inch socket there is an adapter that comes with the microphone

For people that use this for fitness instruction, do you need to use the windscreen? I will be teaching Jazzercise but do not want to use a windscreen

If you sweat gets in the microphone it will damage the unit. I went through a half dozen of these before I came up with an answer to the problem. The windscreen is the first line of defense working as a sweatband. Not to mention heavy breathing.

How can you connect this to an iPhone and use it in a pool?

The system works with an iphone. What you need to bring is an original lightning to 3.5mm adapter cable, such as ASIN-B01LXJFMGF Only the condenser and gooseneck can be submerged in water, the transmitter part is not waterproof. So if you're doing some movement teaching by the pool, that's fine. But it can't be taken into the water.

Can i use this charger with my fitness wireless microphone, kimafun 2.4g wireless waterproof headset microphone with transmitter and 3.5mm receiver,

i don't believe so, its only compatible with what it comes with.
