Answer 1

You can use a simple loop:

suffix = []
out = []
for l in list_:
    if l[0].startswith('CORAM'):
        suffix = l
    else:
        out.append(l+suffix)
out

Output:

[['1',
  'CC006000000196545',
  'P99000007726',
  'Jennifer Nilesh Joil',
  'Viva Homes Pvt. Ltd.',
  '30/10/2021 @ 11:00 AM',
  'For Appearance',
  'CORAM: ThaneBench1'],
 ['2',
  'CC006000000196225',
  'P51700001729',
  'Sheth Developers Private Limited',
  'Mr. Rahul Sirkhe and Mrs Pomy Nandy',
  '30/10/2021 @ 11:45 AM',
  'For Appearance',
  'CORAM: ThaneBench1'],
