某房屋建筑工程项目，建设单位与施工单位按照《建设工程施工合同(示范文本)》签订了施工承包合同。施工合同中规定：
(1)设备由建设单位采购，施工单位安装。
(2)建设单位原因导致的施工单位人工窝工，按18元/工日补偿，建设单位原因导致的施工单位设备闲置，按表5—18中所列标准补偿。

表5—18设备闲詈补偿标准
机械名称	台班单价/(元/台班)	补偿标准	机械名称	台班单价/(元/台班)	补偿标准
大型起重机	1060	台班单价的60%	自卸汽车(8t)	458	台班单价的50%
自卸汽车(5t)	318	台班单价的40%

(3)施工过程中发生的设计变更，其价款按建标[2003]206号文件的规定以工料单价法计价程序计价(以直接费为计算基础)，间接费费率为10%，利润率为5%，税率为3.41%。
该工程在施工过程中发生以下事件。
事件1：施工单位在土方工程填筑时，发现取土区的土壤含水量过大，必须经过晾晒后才能填筑，增加费用3000元，工期延误10d。
事件2：基坑开挖深度为3m，施工组织设计中考虑的放坡系数为0.3(已经监理工程师批准)。施工单位为避免坑壁塌方，开挖时加大了放坡系数，使土方开挖量增加，导致费用超支1000元，工期延误3d。
事件3：施工单位在主体钢结构吊装安装阶段发现钢筋混凝土结构上缺少相应的预埋件，经查实是由于土建施工图样遗漏该预埋件的错误所致。返工处理后，增加费用20000元，工期延误8d。
事件4：建设单位采购的设备没有按计划时间到场，施工受到影响，施工单位一台大型起重机、两台自卸汽车(载重5t、8t各一台)闲置5d，人工窝工86工日，工期延误5d。
事件5：某分项工程由于建设单位提出工程使用功能的调整，须进行设计变更。设计变更后，经确认直接工程费增加18000元，措施费增加2000元。
上述事件发生后，施工单位及时向建设单位造价工程师提出索赔要求。
[问题]

分析以上各事件中造价工程师是否应该批准施工单位的索赔要求为什么
