first and second is dwarf alberta spruce ... picea glauca conica ... and about 3 to 4 feet too close to the fence ... ken

3rd is Sierra redwood. Although a bit open in habit 4th looks otherwise quite like dwarf Alberta spruce also.

I agree on all of the above.

I think the 4th one looks a bit open because it's very young. One more growing season should 'fix it'.

Yes.

#3 is a Giant Sequoia (Sequoiadendron giganteum)

Hamza, here is Dwarf Alberta Spruce. See my baseball cap for scale. Your 59P plant may look like this after several years.
Unfortunately in the USA, many DASs look like this in time, possibly a repeated mite infestation which happens when it becomes hot and dry.

Those two pictures are so spot on in displaying the two sides to this variant. They can be quite beautiful when healthy and happy, but far too often they are hit with some malady. Mine are too open, and winter sun will do a number on them. Some woody plants are better than others in hiding their shortcomings (just like people)...not so much for DAS.
