Sharing limits- 
You can explicitly share a doc or file with 200 viewers and editors.
Only 50 people can edit and view a document, spreadsheet, presentation, or drawing at the same time. Additional viewers will still be able to preview the item, but they won't be able to edit it, and they won't be visible to others working on the item.
Functions available in Google Spreadsheets
Each spreadsheet can be up to 256 columns, 200,000 cells, or 100 sheets, whichever is reached first, to be converted to Google Docs format. There's no limit on rows.
