Objectをループさせて条件判定するときはarrayに変換してsome()とevery()を使うと便利

function isArrayActive(obj) {
  return Object.keys(obj).some(function (key) {
    return obj[key] ? true : false;
  });
}

// 無効ユーザ
const user = {
  name: "",
  type: "",
  flag: false,
  data: null
};

// 有効ユーザ
const user2 = {
  name: "Tanaka",
  type: "",
  flag: false,
  data: null
};

if(isArrayActive(user)) {
  console.log("active");
} else {
  console.log("not active");
}


if(isArrayActive(user2)) {
  console.log("active");
} else {
  console.log("not active");
}

// not active
// active

function isUserActive(user) {
  const isActive = {
    name   : user.name             ? true : false,
    type   : user.type === "human" ? true : false,
    upload : user.upload           ? true : false
  };
  // Objectの要素全てがtrueであればtrue、ひとつでもfalseがあればfalse
  return Object.keys(isActive).every(function (type){
    return isActive[type];
  });
}

const user = {
  name   : "",
  type   : "",
  upload : false,
  data   : null
};

const user2 = {
  name   : "Tanaka",
  type   : "human",
  upload : true,
  data   : null
};

console.log(isUserActive(user));
console.log(isUserActive(user2));

// false
// true

if(isActive.name && isActive.type && isActive.upload) {
  return true;
}
