Ametrine? Though I'm picking up smokey quartz vibes..

Either a dyed stone, or... Blue Quartz/Dumerdorite. It doesn't look like an agate to me.

As for the black stone... If it is extremely light like Styrofoam, it is Jet. Otherwise it is Black Obsidian.

Thank you so much, I'm pretty positive that the black is Jet, the clear crystal is quartz, and the blueish is a blue agate. The other two I'm not positive of.
Here's some better pictures of the last two:

This is the best I can get picture wise. I might just have to go back to the store.

Those pictures helped quite a bit.

The first, I would take to the shop. Smokey quartz and natural citrine are nearly impossible to tell apart from the naked eye.

The second one, now that I see the details and the specific blue, can say that it is sodalite.

Here's a picture of what sodalite looks like:

Image Search the gemstone names everyone gave you, and compare them to what you have.

1st one is definitely a clear quartz

2nd one looks like an amethyst to me, that is if it is purple. Is it purple? I have a tumbled stone which kind of looks like yours, and it is an amethyst.

3rd one looks like a blue sapphire to me. But I am not sure.

4th one could be a smokey quartz.
:/

To be sure contact the store where you purchased them. If it was an online shop they will have a copy of the order. If you bought them from a physical shop take them back and ask them.
