yes, bacteria do have cell walls.
not only that it also has plasma membrane, s-slayer, and some even have capsule.
it is true that there are two type of bacteria: gram positive and gram negative.
gram positive have a THICK layer of peptidoglycan, thus it has a THICKER CELL WALL. Gram negative on the other hand, have thin peptidoglycan and it has a a space between the plasma membrane and the cell wall. thus, gram negative do have cell wall but their cell wall is very thin when compare to gram positive.

The peptidoglycan layer is generally referred to as the "cell wall". Gram positive bacteria have a thick peptidoglycan layer and are thus considered to have a "cell wall". Gram negative bacteria have a very thing peptidoglycan layer and are thus considered to not have a cell wall, but have a double membrane.

No, cell walls are for plants. They do, however, have one membrane surrounding the whole cell.
