Probably with lower voltage. Some capacitors may accept far more voltage,
but it is a question of luck.

If they have some kind of varnish over them, probably yes.

Your coil looks rather small for a Tesla coil.

The coil is probably working, but at low voltage due to the small number of
turns in the secondary coil and/or imperfect (any?) tuning.
