#2 is a Fragaria, or strawberry. Is this for a school project or consulting? 4 looks like a Castilleja, 5 a Potentilla.
Thank you, Daniel Mosquin! #2 must be a Fragaria vesca (alpine strawberry). It is for a school project. #4 Castilleja without a flowerhead, hmm.. #5, not Potentilla recta (sulphur cinquefoil) nor Potentilla flabellifolia (fanleaf cinquefoil)..
