How many social sharing plugin Should i use in Wordpress?

I see a lot of website with a lot of sharing plugin installed. I am curious to know does having so much plugin do increase the share count?

By a lot of plugins meant these common plugin people install :-

• floating type sharing plugin
  
• above content share icons
  
• below content share icons
  
• on images (Pinterest share )
• Instagram feed sharing tool
  
• twitter, G +. fb page feed plugins

is it really worth it? does have multiple sharieg plugin increase the share count?
From where most of the organic share come from ? which part of the content

If anyone observe the social share increase after installing a new type of sharing plugin, do tell me

Thank you for BHW for your support.
