Also you can cast vTexIndex to int.

int textureIndex = int(vTexIndex + 0.5);

if (textureIndex == 0) {
    finalColor = texture2D(textures[0], gl_PointCoord);
} else if (textureIndex == 1) {
    finalColor = texture2D(textures[1], gl_PointCoord);
} else if (textureIndex == 2) {
    finalColor = texture2D(textures[2], gl_PointCoord);
}
