Hi, @jonelle-forbes – Hope you don’t mind that I moved your post into the ‘What Is It’ forum. Do you have any further information you could share about these finds (city/state info, did you find any of these on the beach, etc.)?
From a quick glance, it appears that you have quite a lot of quartz/agate pebbles. Quartz comes in many different colors (see here: http://www.minerals.net/mineral/quartz.aspx).
Your second picture appears to have mostly modern invertebrate shells and coral pieces. The specimens at the top of that picture might be fossilized, but I’d need individual pictures (with something for scale — do you have a penny?).
