I might start checking if the Services Accounts has the same roles and privileges among the projects.
Also please check if the Network Tags attached to the VM instances are correct (syntax) and the corresponding Firewall rules for ingress/egress are allowing the icmp traffic.
You can check Firewall rules in GCP: Source and Target filtering by Service Account and Filtering by service account vs. network tag for more details. Please note you cannot mix and match service accounts and network tags in any firewall rule.
I recommend you to review the Use Cases for Ingress and Egress described here.
Additionally, in this document are described common scenarios where Multiple Network Interfaces are used. It might help you to build a Networking and virtual appliances by different Nic devices, Shared VPC and so on.

Thank for your answer. I already mentioned Firewall allow ping for all targets from all source. So firewall is not problem in my case. Furthermore, when applyfirewall ruleI already can see 3 GCE instances that follow a rule.

1. For the test02 and test03, on the "Network details", double check each Egress and Ingress firewall rules and Routes configuration. 2. Compare the configuration amoun the 3 VMs.
