one of them will be server (collecter)

15 pcs of them will be client(data sender)

Hello,

According to the S140 SoftDevice Specifications, it should be able to handle up to twenty connections concurrently.

Hello,

Yes, of course. In the nRF5 SDK 15.2, under ble_central in examples, you'll find the ble_app_multilink_central which acts as the server. And under ble_peripheral in examples, you'll find the ble_app_blinky which acts as a client. 

In the SDK 15.2 folder, you'll find more documentation on the Multilink example.

Edit: This tutorial in DevZone might be a good starting point.
You can also find similar cases in DevZone, like this one, this and this. If you need more information, try searching for Multilink in DevZone.

Hope this helps!

Best regards,
