Identification of some marbles

[cjmust30]

I know that you guys are always getting tapped for your knowledge, but I just need to be pointed in the right direction for these marbles. I have no clue of the material, make, age or anything about these. I just snapped a few photos because there are many marbles. Thanks in advance.
