#2 some poor sorted conglomerate-sandstone
#3 some volcanic rock, riolite-trahite series
#4 metamorphic rock, schist or gneiss
#5 volcanic rock-tufite??

Praporgescu, you would be helped by borrowing some basic books from the library and looking up these rocks and see if the descriptions match (or google the rock names).
