Clearing price in a double auction market
In your example, the market clearing price is $25$ as there are two buying bids at that price or higher and two selling bids at that price or lower, and no other price achieves this match

So Buyer $1$ and Buyer $2$ both pay $25$ and Seller $1$ and Seller $2$ both receive $25$

If you want actual examples, you could look at the shares of Tottenham Hotspur Limited (the football club) on Asset Match and the Auction results (almost every month) in the right hand column.  The orders are shown cumulatively but it is easy enough to decipher the actual bids at each price.  For example in June 2019 they looked like this

  Cumulative  Actual           Actual   Cumulative           
   wanted     wanted   Price   offered   offered
    11900         0     250p      875        875
    11900         0     260p      500       1375
    11900      7900     265p     9842      11217   
     4000      2500     270p    16314      27531 
     1500      1500     275p     1384      28915


The market clearing price was $265$ covering $11217$ shares as this is where the cumulative supply and demand curves cross.  The successful trades included all those shares offered at $250$ and $260$ and $265$, and all those wanted at $275$ and $270$ plus $7217$ of the shares wanted at $265$.  All successful transactions were settled at $265$, though the Assetmatch would have then charged a small fee for arranging the deals
