Is this rude??

So I’ve been thinking about my timeline for the wedding evening and in order to keep everything on time I think there may need to be time limits to each speech.... my questions are


1. What is a normal amount of time for each speech??
2. Is it rude to give my people time limits to their speeches or should I just let them have as much time as they want and risk going over time??
3. If its not rude, what’s a good way to tell my people about their speech time limits without sounding like a Karen?
I know my bestie/MOH is totally fine with me telling her anything so I’m not worried about her at all we are super open and close and always on the same page.
The rest of the speeches will be from: my FHs parents (they asked if they could)my FHs best man aka brother. My dad.Our 2 friends-husband and wife- are playing our first dance acoustic and they asked if they could give a speech which we obviously and happily said yes to. Also me n my fiancé’s introduction/“thank you for being here” speech to our guests.
