Can I run these appliances with 25A
You have not provided enough information to get a detailed look but we can play with some estimates. I am using watts for power consumption, which we will use to calculate amps at the end:

Some of the items we can guess pretty well:

10 laptops (80 watts each)       800 watts
1 external monitor               100 watts
9kBTU air conditioner            1000 watts
13kBTU air conditioner           1400 watts
2 fans (50 watts each)           100 watts
1 mini fridge                    400 watts
internet router                  20 watts


That adds up to 3820 watts, or around 16 amps @ 240V.

The other items are harder to know. Lighting depends HUGELY on the amount of space you're trying to light and the type of bulbs. A small office lit with LEDs may use only 100 watts, but a large space using old-fashioned incandescent bulbs will use much much more.

Also, I have no idea what an air cooler is so it's hard to get a value for that.

And obviously your "misc" category could include anything...

But I would say as a rough cut that 25 amps is probably enough, assuming you don't blow your power budget on lighting.
