These are more from Grandpa's collection. The 2 in the middle feel tumbled. The 2 on the outside have that soapy feel.
The 3rd rock is a dark gray and red. The 4th rock is pink and medium gray. Thank you.

Probably all forms of cryptocrystalline quartz. The brick red one we would probably call Jasper, the one with the sharp edges at the top is a chert with typical conchoidal fractures. The spotty red one between the two could be another jasper. The final one is a tumble-polished rock.
As Steve B pointed out in his inimitable way though, you would be well-served to do some basic tests yourself as in general pictures do not serve well...it happens that the two I've positively ID'd are pretty obvious. Plus in doing the tests, you will educate yourself in the lore and practice of mineral collecting...
