Identify Aquatic Grass Seeds?

A few years ago, i had bought seeds online that said they were "aquatic plant seeds", but after trying them, they didnt grow, i wasnt sure if i was scammed or i did it wrong. (This was before i thought of asking forums)

After uncovering them in my storage room, i wanted to confirm if these were aquatic plant seeds or not, and whether or not they can still be planted.

You could try a few on wet earth in a shallow tray with water and see what you get. You have a strange variety of seeds there.

any type of earth? and how shallow should the water be?

I have never grown aquatic plants from seeds, but I'm far from Malaysia! I would use any type of soil covered with maybe a centimetre of water. No fish would be involved. I would just want to see what grew.
@connorlindeman has a plant business, and he is more likely to have experimented or read on these techniques. So hopefully by tagging him, we can get a more learned response.

The vast majority of these seeds are a scam.
Most of the time they recommend starting with a dry start technique to allow the plants to sprout. You will see a nice thick carpet grow, but once you flood the tank, they will die.
If you plant in a established aquarium, the seeds will rot causing water quality issues. Ammonia will spike causing death.
Most seeds packs are mislabeled. Products advertised as “aquarium carpet seeds” typically contain terrestrial weed seeds that may sprout briefly but die off once submerged, or never sprout.
A small number of proper aquatic species, like Glossostigma elatinoides or Lobelia cardinalis can be grown from seed, but the easiest way to propagate carpeting plants is via cuttings, not seeds. Collecting such seeds is labor intensive and not cost effective for sellers, so legit seeds will be quite expensive.

Taking a closer look at your pictures, and those are definitely not aquatic plant seeds. One appears to be grass seeds, and the other possibly Brassica. Both terrestrial plants that you do not want in your aquarium.
