When I see all these sentences above, three questions arise in my mind:
1. Can I use ‘to’ or ‘on’ to replace ‘for’ in sentences1-4?
2. Can I use ‘for’ to replace ‘to’ or ‘on’ in sentences5-9?
3. Are there any rules telling us when to use ‘to’ ‘on’ or ‘for’ after ‘limit(s)’(noun)?

Thanks very much in advance.
