I have used the terraform vpc module from registry to create vpc and subnets as follows:

#https://registry.terraform.io/modules/terraform-aws-modules/vpc/aws/latest
module "vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "2.77.0"
  # insert the 49 required variables here
  name            = "${var.vpc_name}"
  cidr            = "${var.vpc_cidr}"
  azs             = "${var.azs}"
  private_subnets = ["10.0.0.64/26", "10.0.0.128/26"]
  public_subnets  = "${var.public_subnets}"

  enable_dns_hostnames = true
  enable_dns_support   = true

  enable_nat_gateway = true
  single_nat_gateway = true

  private_subnet_tags = {
    Name = "nprod-net"
  }
}

As you can see I have 2 private subnet with tag "nprod-net" but I want to name each private subnet with a different name say "nprod-net-app-1a" and "nprod-net-vpce-1a". Any help would be appreciated.

You can not customise tags for each private subnet because the module just accept list of tags for all private, but after creating the subnets you can leverage aws_ec2_tag resource to tag the subnets again, for example:

resource "aws_ec2_tag" "private_subnet_tag" {
  resource_id    = module.vpc.private_subnets[0]
  key            = "Name"
  value          = "nprod-net-app-1a"
}
