can this hold cr2025 batteries?

Yes, as they are the same diameter, just a little thinner. You could also add a washer or something for a shim if not thick enough.

Can anyone tell me how many small led lights one of these can illuminate without killing the batteries super fast?

I tried 3 LED wired in parallel and it last more than 2 weeks with about 2 hours/ day.

What do most people use these for?

use for anything that needs voltages and currents that a coin cell can supply. also use a s a temporary substitute when changing the original or later batteries in a device that requires a voltage for a memory chip not to lose its memory, etc. Also nice to just stare at and maybe hang on the wall.

Could someone kindly provide more specific instructions on how to connect to an led light set for christmas sweater? thanks.

Solder red wires together and black wires together. Install batteries and flip the switch on. If you don’t know how to solder, I would suggest twisting them tight and heat shrinking them with tight heat shrink
