It's not at all clear what your problem is.

For the unique number - why not just have an identity column on the database table?

Nested loops.

If i understand you correctly you want to increase ReciptNumber for each selected row in DataFridView. So, you need only one loop:
VB
Dim ReciptNumber As Integer = 0
Dim mixReciptNumber As Integer = ReceiptEntryTableAdapter1.ScalarQuery1("BILL")
ReciptNumber = mixReciptNumber 
For Each Row As DataGridViewRow In DataGridView1.SelectedRows
    ReciptNumber = mixReciptNumber + 1
    'insert part
Next
