First picture looks like a Calcium stalactite, or stalagmite, with an iron staining. Second ones, hard to tell. Looks to be from a pegmatite, but pictures are not concise enough to say for certain. Only way to determine certainty, is to hit with either a Geiger counter, or XRF with proper software. Most Pitchblende, from pegmatites, is usually black. Uraninite is yellow, and usually found in sandstone replacement deposits. You could also try a UV light, see if it fluoresces a light green.
