Answer 1

Finally tsc started working without any errors. But multiple changes. Thanks to Sandro Keil, Pointy & unional

• Removed dt~aws-lambda
• Removed options like noEmit,declaration
• Modified Gruntfile and removed ignoreSettings

tsconfig.json

{
    "compileOnSave": true,
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "noImplicitAny": false,
        "strictNullChecks": true,
        "alwaysStrict": true,
        "preserveConstEnums": true,
        "sourceMap": false,
        "moduleResolution": "Node",
        "lib": [
            "dom",
            "es2015",
            "es5",
            "es6"
        ]
    },
    "include": [
        "*",
        "src/**/*"
    ],
    "exclude": [
        "./node_modules"
    ]
}

Gruntfile.js

ts: {
            app: {
                tsconfig: {
                    tsconfig: "./tsconfig.json"
                }
            },
