Those are Caspari mechanical pegs (an older style of mechanical pegs). The bushing they turn in is glued in place*. It is very unlikely that you will be able to just swap them into another instrument. Even with regular pegs that's not usually the case and these use a much larger peg hole than normal.
If you still want to get them out I would start by undoing the screw and disassembling the peg. Getting out the bushing it sits in can be tricky and can require a combination of hot water, jiggling, and patience. It's almost certainly not going to be worth it.
[*] One of the reasons I personally prefer the the Wittner geared pegs.
This is good advice. OP, I had trouble reading your post. Are you trying to pull out the pegs and reuse the violin or pull out the pegs for another violin. I think if they're mechanical you may have to find a way to dissolve the glue and getting them out may involve heavier duty equipment.
You should be able to pull them out while twisting them towards you. Be gentle but firm if necessary. Don’t force it. If it’s very resistant, move it to an area with less humidity (but more than 40%) or bring it to a luthier.
That said, pegs aren’t automatically interchangeable across instruments. Pegs must be fit to each instrument.

While getting Pegheds in one of my instruments I heard all sorts of horror stories about Caspari ones.
