Would these work to replace suction cups on metal sponge holder for sink?

I have no idea, I bought them for the feet of a spong bean slicer. Sadly the suction was not very good so I am contemplating screwing it to a piece of wood and securing that by G clamp to a work surface. Hope this helps you make the correct decision.

Would these stick a glass cup to the dashboard of a car

Nope, these suction cups are too small to hold the heft of glass of water. You need a larger size.

Does anyone know what weight these would hold? Looking to use in resin craft to hold a window piece in place. Piece weighs 40g - 50g

Very small and very light weight. 40 / 50 gm would be pushing it. I think you would need something more substantial.

have a glass topped cast iron dining table will these suction cups fit through the hole in the frame

could you be more specific please?e.g. no idea how the iron cast frame looks like.- they pretty small at 20mm diameter and you can fold them little bit as well so it could fit trough opening of 15mm or little smaller
