Cannons from front to rear are: 10-Inch Confederate Columbiad, 10-Inch Confederate Columbiad, Brooke Rifle (caliber uncertain), 10-Inch Columbiad Model 1844 Banded and Rifled, 8-Inch Siege Howitzer Model 1841. Fort Sumter can be seen in the distance. Photo available here: https://www.loc.gov/item/2018666897/
Fort Johnson, which dated to colonial times, had fired the "signal" mortar round at the beginning of the Bombardment of Fort Sumter, and which had been a major component of the defenses of Charleston harbor - especially after the reduction of Fort Sumter, was photographed in 1865. These photos, available in high resolution on the Library of Congress website, show the four heavy cannons facing the shipping channel, along with carriages, implements, projectiles, and more.
While much of what is pictured is no longer at the site, a brick magazine which dates to 1765 still stands.
The Banded and Rifled 10-Inch Columbiad in these photos still exists - it is displayed at Fort Sumter. More information on this cannon may be found here: https://www.santee1821.net/preserved-artillery/10-inch-model-1844-columbiad-banded-and-rifled-at-fort-sumter
The other three heavy cannons in this photo: two 10-Inch Confederate Columbiads and one 7-Inch Brooke Rifle may be among the survivors of those types still in Charleston.

Detail of Brooke Rifle from previous photo
Interior of Fort Johnson in 1865. I believe this photo to be taken behind the left 10-Inch Columbiad (when looking out towards the channel). Note the round shot for the two Columbiads. Also note the stacked rifle projectiles to the left of the tent. I believe those to be the same as seen in the previous photo of the Brooke. Photo available here: https://www.loc.gov/item/2018666899/
