Name of strength training exercises

I have started using weights. My problem is I don't know the proper name for them and can't log them successfully in my fitness diary, I have to keep entering bicep curls.

I do 6 different ones. I've tried googling them, have even found some but when I try to log them in it says no match. Can anyone suggest a website that has the proper names of these arm exercises please? Also there one I do where you stand up straight, arms by your side holding weights and you bend to the side and then bend to the other side - great for your waist but don't know the name of this either. Hope someone can help

Thanks
