What's a good glue to secure these onto plastic or metal? Super glue isn't working well enough.

I sometimes use E6000 glue. It's not a instant bond glue, but it's very strong. I recommend small tubes of the glue so you don't have to worry about it drying out in the tube. I also like to roughen up the back of the pin pads with some sandpaper for extra grip.

Will these work for needle felt brooches? I'm thinking they would make the brooch easier to attach to clothing. Standard brooch pins can be tricky

Assuming a felt backer, i would say Yes, if poked thru the backer and secured prior to the backer being affixed to the Brooch. with this in mind, a tack pin with a larger, maybe 10mm head, and a longer shank might work better. These Tack shanks have a 4.5mm head on a 8mm long shank. something with a 10mm head on a 8-10mm shank might work better, as most felt is 2-3mm thick. this is dependent on the backer material you use of course...

Do these tacks leave holes in the fabric once they're removed? Tack pins I have used before have damaged the fabric.

I believe it depends on the fabric. I used a satin/polyester blend and it did leave holes in my material.
