[Water tank screws]

Hi everyone,

 

I was wondering if anyone could help me with getting these screws off my water tank cover.

 

I'm new to boating and want to clean out and re-paint the water tank to get rid of the rusty water, however there are 3 different types of screws holding the water tank cover one and I can't get most of them off!

 

These are the culprits below (assuming the hosting site works!) What type of screws are they? and what is the correct tool to use to get them off? I have been using mole grips as a last desperate measure with no success.
