new to plants.. and they are dying..

I admit I'm no expert on plants but the first thing you need to do is try and identify the plants. You said you bought bulbs? Do you mean like from petsmart or petco? A lot of those plants aren't actually aquatic but terrestrial and at first will grow fine but then die.

Even if they are aquatic, different plants still have different requirements. Some plants need high lights and a fertilizer regime. Other plants require very little light and live on fish poop alone. Don't concern yourself so much about CO2 right now. It helps but at low levels of light like below 2.0 wpg it's pretty usueless and I suspect you're not using fertilizers. You don't want to do a lot of research and unnecessary work. Your plants also might just be dying because you moved them, so they have to adjust to their new environment. I believe crypts are especially sucsceptible to "melting" which might be what you have here.

Betta bulbs?

That wilted leaf looks like a crypt.

yeah i think that is anubias as well. I forgot to mention that some plants shouldn't actually be buried in the substrate. Burying the rhisozome can lead to plant death. Anubias is one of those plants. It should be tied to wood or a rock instead. I don't recognize any of the other plants sorry.

can you give us lighting paramaters and if you're dosing ferts? People here on the forums are very nice though. I'm sure someone (even me) might be willing to furnish you some easy growing plants and might be willing to do it for free (you pay shipping of course) if most of your plants turn out bad. You need more plants by the way. A lot more.

seems like you paid a lot for the substrate though. What is it? It's very nice. ADA?

If you are thinking about doing diy co2 just check out the stickies in this section. Read it all. You can measure you co2 by taking kh and ph readings. Then look at them on a chart. The kh should stay the same the ph will drop as co2 gets higher. You want to be at the right level so you don't kill fish but enough to help. Also you should find out what light you have in their. for 10 gallons you won't abe to grow anything without 10 watts. 15-20 watts will let you grow a good amount of stuff. You get up to 40 watts and you can grow anything your heart desires. But if your lighting is lower then 10 watts nothing will grow. You need to research what you have. If you got at least 10 watts that anubias might be ok but the rest matter how much light they need I am not familiar with the rest.

As for making sure your GH and KH is high enough to do co2 and how to adjust if they aren't check this site out. Read around the rest of the articles too. Just don't let it intimidate you. Not all plants require crazy high watts or ferts.

last 2 pictures possibly a red lotus?

Lotus is the "mystery plant". I have the same thing in my 5G betta tank. It really took off, and then I introduced a snail that destroyed most of it, though since the snail is no longer there, the plant is coming back.

I did cut back the surface leaves though since I didn't want to block out all the light, and they were taking over.

If you keep those trimmed back, the plant should do well without killing everything else by blocking the light.

Not sure about the rest of your Q's, but the mystery plant is a lotus.

GH isn't important for CO2; KH is, as long as it's above around 3 degrees (50ppm) you're fine. You can't trust the CO2/KH/pH relationship as it only works in a pure water bicarbonate system; any other buffers and/or acids which might be present will push it off course. Best thing is to aim to depress pH by up to 1 full point.

Or use a drop checker.
