First the model

I've changed the measures to:

Rows Values Temp =
VAR _CYProjects =
    COUNTROWS ( ALLSELECTED ( 'Year Table'[dYear] ) )
VAR _ALLProjects =
    CALCULATE (
        COUNT ( fTable[Year] ),
        FILTER (
            ALLSELECTED ( fTable ),
            fTable[Project] = MAX ( fTable[Project] )
                && fTable[Type] = MAX ( fTable[Type] )
                && fTable[Model] = MAX ( fTable[Model] )
        )
    )
VAR _CP =
    CALCULATETABLE (
        VALUES ( fTable[Project] ),
        FILTER ( fTable, _CYProjects = _ALLProjects )
    )
VAR _result =
    IF ( MAX ( fTable[Project] ) IN _CP, SUM ( fTable[Amount] ) )
RETURN
    _result

Common Projects =
SUMX (
    ADDCOLUMNS (
        SUMMARIZE (
            fTable,
            'Type Table'[Type],
            'Project Table'[Project],
            'Model Table'[Model]
        ),
        "@Total", [Rows Values Temp]
    ),
    [@Total]
)

PY Temp =
VAR _PY =
    CALCULATE (
        MAX ( 'Year Table'[dYear] ),
        FILTER (
            ALLSELECTED ( 'Year Table'[dYear] ),
            'Year Table'[dYear] < MAX ( 'Year Table'[dYear] )
        )
    )
RETURN
    IF (
        ISBLANK ( [Common Projects] ),
        BLANK (),
        CALCULATE (
            SUM ( fTable[Amount] ),
            FILTER ( ALL ( 'Year Table'[dYear] ), 'Year Table'[dYear] = _PY )
        )
    )

Growth Rate =
VAR _PYValue =
    SUMX (
        ADDCOLUMNS (
            SUMMARIZE (
                fTable,
                'Type Table'[Type],
                'Project Table'[Project],
                'Model Table'[Model]
            ),
            "@PY", [PY Temp]
        ),
        [@PY]
    )
VAR _result =
    DIVIDE ( [Common Projects] - _PYValue, _PYValue )
RETURN
    IF (
        OR ( ISBLANK ( SUM ( fTable[Amount] ) ), ISBLANK ( [Common Projects] ) ),
        BLANK (),
        COALESCE ( _result, 0 )
    )

To get:

As for you Req-3, you are not getting values for [Common Projects] and [Growth Rate] because thare no projects for model B which are present in all three years selected, according to your brief which says:

"When User selects all the Year,(Slicer) Amount will be shown only for those Projects which are common to all the Year."
