    I have a 21.5- inch iMac mid 2011.
    Can I install a 4GB 1333MHz DDR3 ram into left bottom slot or I should fill all the slots? Maybe it is very simple question but I don't want to buy a useless ram.

    AFAIK there doesn't have to be a RAM module in every slot. My workplace has a couple of 2011 iMacs and at least one of them has only 3 of the 4 RAM slots occupied and it recognizes all the RAM that's installed. So I believe you would be able to use a single 4GB module instead four 1GB modules. :)

    I'm thinking it should be new enough to recognize 4GB module. I know the older iMac like mine can only have max of 2GB per slot but thats 2007 model.
    I would almost bet your 2011 can handle max of 8GB or 16GB, so either way the 4GB module you buy should work!
