the one on the left is one piece,but the one on the right is sperate pieces. should they be floating? or should i leave them planted in the gravel?

Both need to be planted on the substrate. One is definitely a Cryptocoryne although I am not sure of the specific species. The other could be ludwigia.

The plant on the left seem to be a crypt of sorts, the plant on the right is Bacopa Carolinia I think.

The plant on the right looks like Bacopa Carolina to me too. It can stay planted in the substrate or left floating on the top of the water. Either way, it does pretty well. If you bought it as a "bunch" plant and it still has a rubber band around it, though, you'll want to remove that. I found that when Bacopa stays bunched together the rubber band causes damage to the delicate stalks and they just tend to rot. Hope this helps.

Theone on the left probably a crypt though could be an off species sword.

The one on the right looks like and emersed form of Ludwigia, either repens or breveps. If it is, don't be surpised if you see a lot of it die off
to start out because the emersed form will die while the submerged form starts to grow in well. If you see some die off and a new form of leaf
growing, let it grow for a little while and then trim it off and replant the new stuff.

thanks for the help, i wasn't sure if i was suppost to let them float or plant them. :wink: cause the one on the left looks like it's starting to die.

What you're seeing isn't actually the crypt dying, but the leaves melting off, in a phenomenon commonly called "crypt rot". Crypts are very sensitive to changes in water parameters and movement. The leaves often rot off as soon as they get into the new tank. However, don't worry, it'll grow back bigger and healthier than before.
