Stacking / Nesting Elements

Hi again. I didn't get an answer to my question yesterday, and now I have a slightly different question....

I want to stack / nest fields in a custom field group. can I do these configurations or will I get problems?

OPTION #1

Tab 1 = Tab option at top of input form

Group 1 = First grouping of fields
     Text 1 = General text entry
     Text 2 = General text entry
     Text 3 = General text entry

Group 2 = Second grouping of fields, Inside Group 1
  Select 1 = Options list
  Select 2 = Options list
  Select 3 = Options list

Group 3 = Third grouping of fields
Text Area

OPTION #2

Tab 1 = Tab option at top of input form

Group 1 = First grouping of fields
     Text 1 = General text entry
     Text 2 = General text entry

Tab 2 = Left aligned tab 1
      Text 3 = General text entry
      Text 4 = General text entry
      Text 4 = General text entry

Tab 3 = Left aligned tab 2
      Select 1 = Options list
      Select 2 = Options list
      Select 3 = Options list

Group 2 = Second grouping of fields
      File Upload 1 = General file
      File Upload 2 = Image file
      File Upload 3 = General file

Group 3 = Third grouping of fields
Text Area
