To me, they look like zeolite mineral clusters, a group of minerals formed within basalt. It's a really cool find, and there is likely more than one kind of mineral with a similar composition, which is common for zeolites. Where did you get it/find it?

Hard to tell because the pictures are so small. Though I do agree with @weasel about the zeolite assertion. Perhaps heulandite or stilbite. If @Alexxander98 posts large pictures we can have a closer look at the crystal structure and nature. The others also appear to have quartz in them, though hard to tell for certain with the small pictures.
