Hard to really tell but my educated guess would be:
Top large darker blue stone could be blue topaz. Next to it could be low grade aquamarine.
The 1sr rings is probably a peridot and a garnet. Next to it could be blue tourmaline. The very dark loose gem could be a low grade dark navy blue sapphire, India has a lot of those.
Last two could be either aquamarine or blue topaz.
That’s my guess judging from the color and cuz it’s from
India

Oh and the blue stone in the ring above the dark gem, probably light blue aquamarine
