The first two are fabric movers - I guess you would call them that. You place them on top of your fabric and use them to help guide your fabric under the needle when you are machine quilting.
The 'pink thing' is a cutting mat restorer. You go over your cutting mat to smooth out the cuts and clean away the threads that are always left.
I don't know about the turquoise things. Maybe a rotary cutter sharpener? HTH
