1. A multi-faced ladder assembly comprising: four individual ladders, each ladder comprising a pair of vertical posts and a plurality of steps positioned between the pair of vertical posts, each ladder having a maximum width at the greatest distance between the pair of vertical posts, each step comprising an exterior portion, each vertical post attached to one vertical post of a different ladder;a substantially square top platform having four sides, each side positioned over and attached to a top portion of one of the four individual ladders, whereby four individuals may climb to the top of the four different ladders simultaneously;wherein each vertical post is detachably attached to an adjacent vertical post of a different ladder with a ladder securing means, whereby when each vertical post is detachably attached to an adjacent vertical post of a different ladder with the ladder securing means, a distance between each vertical post and the adjacent vertical post of the different ladder is less than the maximum width of each ladder;wherein the four individual ladders collectively form a substantially contiguous structure substantially along a perimeter of the top platform, whereby the multi-faced ladder assembly comprises a substantially pyramidal square frustum shape, whereby each of the four individual ladders is positioned directly opposite one other ladder of the four individual ladders; andwherein the exterior portion of each step faces outwardly away from a center of the substantially square top platform. 2. The multi-faced ladder assembly of claim 1, wherein the top platform connects to the top of each of the four individual ladders via a locking means. 3. The multi-faced ladder assembly of claim 2, wherein the locking means comprises at least one of a hinge, clasp, clamp, screw, rivet, clip, cable, hook and loop fastener, snap, strap or combinations thereof. 4. The multi-faced ladder assembly of claim 1, wherein the height of the ladder assembly is between about six feet to about fifty feet. 5. The multi-faced ladder assembly of claim 1, further comprising: a central utility storage unit attached to a bottom surface of the top platform. 6. A multi-faced ladder assembly comprising: four individual ladders, each ladder comprising a plurality of horizontal steps positioned between a pair of vertical posts, each ladder having a maximum width at the greatest distance between the pair of vertical posts, each horizontal step and each pair of vertical posts comprising an exterior portion, and;a substantially square top platform having four sides, each side positioned over a top portion of one of the four individual ladders, and connected to the top of each of the four individual ladders via a locking means, wherein the exterior portion of each of the plurality of horizontal steps faces outwardly away from the substantially square top platform, whereby four individuals may climb to the top of the four different ladders simultaneously;four support platforms, each support platform comprising a trapezoid shape having a narrower end and a wider end, the wider end positioned at a bottom end of each of the four individual ladders, the four support platforms adapted to extend away from the exterior portion of each vertical post in a direction away from a center of the multi-faced ladder assembly; andwherein each vertical post is detachably attached to an adjacent vertical post of a different ladder with a ladder securing means, whereby when each vertical post is detachably attached to an adjacent vertical post of a different ladder with the ladder securing means, a distance between each vertical post and the adjacent vertical post of the different ladder is less than the maximum width of each ladder; andwherein the four ladders collectively form a substantially contiguous structure substantially along a perimeter of the top platform, whereby the multi-faced ladder assembly comprises a substantially pyramidal square frustum. 7. The multi-faced ladder assembly of claim 6, wherein each support platform is connected via a hinge to the bottom of one vertical post of each of the individual ladders. 8. The multi-faced ladder assembly of claim 6, wherein the support platform comprises a non-skid material on a bottom surface thereof. 9. The multi-faced ladder assembly of claim 6, wherein the support platform comprises a top surface comprising a non-stick material. 10. The multi-faced ladder assembly of claim 6, further comprising: a central utility storage unit attached to a bottom surface of the top platform. 11. A multi-faced ladder assembly comprising: four individual ladders, each ladder comprising a plurality of horizontal steps positioned between a pair of vertical posts, each ladder having a maximum width at the greatest distance between the pair of vertical posts, each horizontal step and each pair of vertical posts comprising an exterior portion, and;a substantially square top platform having four sides, each side positioned over a top portion of one of the four individual ladders, and connected to the top of each of the four individual ladders via a locking means, wherein the exterior portion of each of the plurality of horizontal steps faces outwardly away from the single substantially square top platform, whereby four individuals may climb to the top of the four different ladders simultaneously;four support platforms, each support platform comprising a trapezoid shape having a narrower end and a wider end, the wider end positioned at a bottom end of each of the four individual ladders, the four support platforms adapted to extend away from the exterior portion of each vertical post in a direction away from a center of the multi-faced ladder assembly, each support platform connected to each ladder, respectively, via a hinge, each support platform adapted to move from an open position in contact with a ground surface to a closed position in contact with the ladder, wherein each platform may be locked in the open or the closed position with a locking mechanism;wherein each vertical post is detachably attached to an adjacent vertical post of a different ladder with a ladder securing means, whereby when each vertical post is detachably attached to an adjacent vertical post of a different ladder with the ladder securing means, a distance between each vertical post and the adjacent vertical post of the different ladder is less than the maximum width of each ladder; andwherein the four ladders collectively form a substantially contiguous structure substantially along a perimeter of the top platform.
