Первое, что делает redrawGameWindow, это рисует фон в окне: 

def redrawGameWindow():
   win.blit(bg, (0, 0))
   # [...]

Все, что рисуется перед вызовом redrawGameWindow, является "невидимым", потому что задняя крышка покрывает весь экран: 

if keys[pygame.K_a] and shootLoop == 0:
   ki_stance = pygame.image.load("image/goku-ki.png")
   win.blit(ki_stance, (0, 0))  # <----- "INVISIBLE"

# [...]

redrawGameWindow() # <---- because it is covered here

Загрузка всех изображений при инициализации до применения l oop: 

ki = pygame.image.load("image/ki.png")
ki_stance = pygame.image.load("image/goku-ki.png")

Изменение класса projectile, stance - это новый аргумент конструктора класса. Вам вообще не нужен класс projectile2 (удалить projectile2): 

class projectile():
    def __init__(self, x, y, radius, color, facing, stance):
        self.x = x
        self.y = y
        self.radius = radius
        self.color = color
        self.facing = facing
        self.vel = 8 * facing
        self.stance = stance

    def draw(self, win):
        pygame.draw.circle(win, (244, 232, 104), (self.x, self.y), self.radius)
        image = ki_stance if self.stance else ki
        win.blit(image, (self.x, self.y))

При нажатии SPACE или a спавн снаряд: 

if keys[pygame.K_SPACE] and shootLoop == 0  and len(bullets) < 5:
    #bulletSound.play()
    facing = -1 if man.left else 1
    x, y = round(man.x + man.width // 2), round(man.y + man.height // 2)
    bullets.append(projectile(x, y, 6, (0, 0, 0), facing, False))
    shootLoop = 1

if keys[pygame.K_a] and shootLoop == 0  and len(bullets) < 3.30:
    facing = -1 if man.left else 1 
    x, y = round(man.x + man.width // 2), round(man.y + man.height // 2)
    bullets.append(projectile(x, y, 6, (0, 0, 0), facing, True))
    shootLoop = 1

Если вы хотите показать другой спрайт для игрока, когда нажата a , вам нужно сделать это в player.draw. Например: 

b4Image = pygame.image.load("image/b4.png")

class player(object):
    # [...]

    def draw(self, win):
        if self.walkCount + 1 >= 10:
            self.walkCount = 0

        keys = pygame.key.get_pressed()
        if keys[pygame.K_a]:
            win.blit(b4Image, (self.x, self.y))

        elif not (self.standing):
            if self.left:
                win.blit(walkLeft[self.walkCount // 3], (self.x, self.y))
                self.walkCount += 1
            elif self.right:
                win.blit(walkRight[self.walkCount // 3], (self.x, self.y))
                self.walkCount += 1
        else:
            if self.right:
